Latest Posts

Jesús' passion for trophy hunting began with his first playthrough of GTA IV. Being an avid collector in games, he decided to embark on a mission to find all the collectibles the game had to offer. Upon completing the task and receiving a small box with a trophy, Jesús knew that trophy grinding would become his lifelong hobby. When he's not pursuing trophies, Jesús can be found enjoying retro videogames, channeling his inner chef, or writing sci-fi stories.

Quick Facts

Number of achievements: 84
Percentage of players with all achievements: 1.4%

The Roadmap to Success

Bear with me; knowing what to do here is essential to not having to do more than two playthroughs. A small mistake, and you’ll be forced to play the game again only for a single achievement.

Step 1: Normal Route

It’s important to know that the game has two main routes and five endings, but only three endings count for an achievement. So, in our first step, you’ll go through the Normal Route.

You’ll find it out there as Sunny’s Route, as Sunny is the protagonist’s name in real life (even though you can use any name on him).

To go through the Normal Route, you’ll have to open the door whenever Kel comes to your house. This will give you access to Faraway Town.

During this route, you’ll get these story-related achievements:

Alt+F4
See you, Space Boyfriend…
Good Morning!
Oyasumi.
OHOHOHOHO!!
Buy high, sell low.
When I flex, I feel my best!
Slime Time is Over!
Whale done.

Aside from those, here’s a list of the achievements you can get while in Headspace, in order:

You think you’re clever, huh…
Green Thumb
Littering is bad, recycling is better.
So majestic, so beautiful…
GWAHAHAHA!!
One for the Road
WHAT’S THE BIG IDEA!?!?

They call me SCARETHROW.

After these achievements, then you can go for these in the Real World:

That can’t be good for business.
Math Whiz
Grammar Whiz

The Art of Self-Defense
Bees?
The Very Best
Tummy Full of Fish
When she was here…
Reduce, reuse, and recycle!
Music Connoisseur of Sorts
Universally Loved

And lastly, the ending-related achievements. It’s fair to say that you don’t need to replay the whole game several times to get all the endings, as there’s a Save picnic basket near the moment when you can decide which ending you want to get.

You can get two achievements as there are two endings for the Normal Route:

One more day…
Close your eyes…

Step 2: Hikikomori Route

This time, you’ll be playing the game on the Hikikomori Route. You’ll have to stay home and ignore Kel whenever he knocks on the door to access this route.

Here are the achievements you can get during this route. You can complete all of them during your last day in Headspace, except for the first two, which you must get in Real World.

Good Boy
Minty Fresh
I’ll cherish you all forever
The Brightest Stars
Take Me to the River!
Welcome Home
See you, Space Husband…

Inhuman
Seriously, you’re the coolest!
Minor Imperfection
A bit Less Lonely
The view is pretty nice…
We’ll always be there for you, OMORI.
Anytime is a good time for a picnic!
Foes Filed!

And now, the last ending that counts for an achievement:

There’s something behind you…

After getting all the achievements, you’ll also get the very last one:

It was all a dream…

Omori Achievements

Omori has a total of 84 achievements. So, grab some snacks and a good drink because you and I will be here grinding these achievements for a long while. Let’s go!

Good Morning

Average Percentage: 57.1%
Missable?: No
Difficulty: 0/10

You’ll earn this achievement automatically after finishing the Prologue.

Oyasumi.

Average Percentage: 54.1%
Missable?: No
Difficulty: 0/10

This one is also story-related, and you’ll get it at the end of Three Days Left, as soon as you hit the bed in Real World.

Alt+F4

Average Percentage: 60.5%
Missable?: No
Difficulty: 3/10

This one is an achievement you’ll get after defeating the Download Window, which you can find in Junkyard. It’s not a difficult battle, as this battle works more as an introduction to boss fights.

See You, Space Boyfriend…

Average Percentage: 58.0%
Missable?: No
Difficulty: 6/10

To earn this achievement, you’ll have to defeat Space Boyfriend, the first major boss fight of the game.

How to Defeat Space Boyfriend

Space Boyfriend offers us a battle where he gets Angry, and you can’t take him out of there, so you’ll have to make your team Happy with Aubrey to get an Emotion advantage against him.
You can decrease Space Boyfriend’s attack by using Omori’s Mock.
If one of the team members gets hurt, remember Hero has an ability named Cook, where he bakes a healing cookie (where’s the furnace?). You can only use it on one of the party members, so choose wisely.

OHOHOHOHO!!

Average Percentage: 44.2%
Missable?: No
Difficulty: 8/10

Another boss fight-related achievement. This time, you’ll have to beat Sweetheart, the second major boss fight of the game.

How to Defeat Sweetheart

Sweetheart gets Happy, and you can’t take her out of that state.
This time, you’ll have much more resources to beat her. I recommend equipping Omori with Sad Poem, Trick, Hack Away, and Painful Truth, Aubrey with Power Hit, and Hero with Snack Time as their abilities.
You should also buy several Poetry Books before the battle.
On your first turn, you must use Omori’s Sad Poem on himself, while the rest of the party will use the Poetry Books. This will make the party Sad, so you’ll get an advantage against Sweetheart. After that, use Omori’s Trick and Aubrey’s Power Hit to deal damage and decrease her Defense.

Buy High, Sell Low…

Average Percentage: 40.9%
Missable?: No
Difficulty: 5/10

To get this achievement, you’ll have to defeat Mr. Jawsum, the third major boss fight of the game.

How to Defeat Mr. Jawsum

Mr. Jawsum is a weak boss with not-so-many strategies besides setting a wall of Gator Guys in front of him to protect himself from damage.
Using Multi-Targeted moves and Follow-Ups like Kel’s Pass To Hero, Kel’s Run’N’Gun, or Aubrey’s Wind-Up Throw is ideal in this battle.

When I Flex, I Feel My Best!

Average Percentage: 40.7%
Missable?: No
Difficulty: 5/10

This time, you’ll have to beat Pluto (Expanded), a boss fight you’ll have right after beating Mr. Jawsum, to get this achievement.

Pluto is relatively easy to beat, as you can set your party up as you do against lesser boss fights; Use Kel’s Airhorn to make all the party Angry, then use Omori’s Sad Poem to make Pluto Sad. After that, use Aubrey’s Power Hit to decrease its defenses and Omori’s Mock to decrease its attack. It should be more than enough.

Slime Time Is Over!

Average Percentage: 37.5%
Missable?: No
Difficulty: 7/10

You’ll have to defeat the Slime Girls to earn this achievement. This one is a boss fight you’ll encounter in Humphrey.

How To Defeat The Slime Girls (H4)

The slimy trio will usually attack by throwing different bottles at the party that will deal damage and change the target’s Emotion. To avoid getting outplayed, you should have plenty of Emotion-changing items in your inventory. This way, you keep your Juice up.
Midway through the battle, the trio will use a move that will swap your party’s HP and Juice and then deal damage to all the kids with a multi-target attack. Try to keep both Juice and HP up during the battle.
During the last phase of the battle, they’ll use a move that will deplete everyone’s Juice, and after that, they’ll make a powerful attack. You can continue without Juice if you deal constant damage and keep your Energy bar up to perform a Release Energy Follow-Up.

Whale Done.

Average Percentage: 37.2%
Missable?: No
Difficulty: 8.5/10

This one is a very challenging achievement, as you’ll have to defeat Humphrey in a battle to get it.

How to Defeat Humphrey

The battle against Humphrey consists of three stages, the first is Swarm, then Grande, and then you’ll battle against its Face.
Humphrey is all about brute force, so you’ll have to use all your resources to decrease its Attack and Defense while setting up an Emotion advantage to take it down. It’s a long battle, where you’ll have to use many items to heal and get more Juice.
Use the Release Energy Follow-Up as often as possible, and you’ll be fine.

Good Boy

Average Percentage: 7.3%
Missable?: No
Difficulty: 1/10

Average Percentage: 38.1%
Missable?: Yes
Difficulty: 1/10

You’ll get this achievement after completing Berly’s Tetherball quest and then going to the Otherworld for the first time. To complete Berly’s quest, you must talk with her in the Playground. Berly tell you Van sent the tetherball flying towards the Vast Forest.

The ball isn’t far away; from the Playground, go south and then head west to reach the Vast Forest. After that, keep traveling to the west but only through the bottom path. Eventually, you’ll find a slight detour with a bridge. There, you’ll find the ball.

As you find the tetherball, return to the Playground, go through the cutscene where Berly teaches Aubrey to do Headbutts, and then go to the Otherworld. You’ll get there from the Playground if you go north and then head east. There, you’ll find a ladder you have to climb.

As you reach the Otherworld, you’ll see a short cutscene where Kel uses Aubrey’s Butt Certificate (What a name…) as a conquering flag, Neil Armstrong-style. That’s when you’ll get the achievement.

Recycling Is a Concept.

Average Percentage: 3.4%
Missable?: Yes
Difficulty: 7/10

You’ll have to recycle 50 trash pieces in the Recycling Machine on the Otherworld to earn this achievement.

Go to Otherworld Campsite and then head east. Eventually, you’ll see a small zone filled with Traffic Cones. If you cut them all and talk with the Sprout Mole hidden there, the Mole will scold you for being a busybody, and you’ll get the achievement. Privacy, please!

Average Percentage: 14.0%
Missable?: Yes
Difficulty: 3/10

You’ll have to complete the Weeping Willow Quest to get this achievement. To do it, go to the first room of Pyrefly Forest, where you’ll see a waterfall and a yellow book. You can interact with the waterfall by throwing some clams there. If you do, the Weeping Willow will appear, asking you to tell her a good joke. After that, take the yellow book.

The next step is to travel to the Last Resort. If you turn right at the entrance, you’ll see a big JOKE post. Interact with it and then return to the Weeping Willow’s Lair.

Lastly, give Hero the party’s lead, tell her a joke, and you’ll earn the achievement.

Everyone’s a Critic.

Average Percentage: 5.2%
Missable?: Yes
Difficulty: 5/10

The choir’s Maestro will ask you for help; that’s when Kel will come into action. You’ll have to play a minigame where you have to throw tomatoes at the Moles to keep them awake. The best moment to throw tomatoes is when they are closing their eyes. You’ll notice it as you start playing!

You’ll have to complete the Rain Town Quest to get this achievement. Rain Town is a secret location hidden in a water puddle in Orange Oasis.

As you enter Rain Town, the Veggie Kids that live there will ask you to adjust a valve so they can be comfortable there. So, your mission is to turn the valve to the right. That’s all you have to do.

By the way, if you turn the valve to the left, you’ll flood the place, killing all the kids and making the area inaccessible. Cool, right?

Ain’t Nobody Here but us Chickens

Average Percentage: 6.3%
Missable?: Yes
Difficulty: 2/10

To earn this achievement, you must defeat the “Chicken?” in the Dino’s Dig.

This is tricky because the “Chicken?” will run away when they sense danger. So, to land a hit on it, equip Omori with a Daisy and use Omori’s Lucky Slice when you get into battle. This will make Omori hit first, defeating the “Chicken?” and granting you the achievement.

The Currency of the Future…

Average Percentage: 9.8%
Missable?: Yes
Difficulty: 1/10

You’ll earn this achievement after trading all your Clams for Clems, a currency as viable as the NFTs in real life. What a scam!

After two turns, he’ll switch to Neutral once again, so the battle gets into a cycle.

Missable?: Yes
Difficulty: 7/10

This time, you’ll have to defeat Pluto and The Earth in a battle to get this achievement. This Tag-Team appears in the shortcut to the Junkyard and only during the One Day Left chapter.

The battle is simple; The Earth’s strategy is to set every of your party members Sad, or even Depressed, to use multi-target moves on you. The thing is that The Earth has no further control over emotions, so you can set it Happy to get an advantage against it. Do the same with Pluto and brute force them to win.

Defeat Mutantheart to get this achievement. This battle is only available in the Normal Route, and you can fight against her after helping Marina with her side quest.

The battle against Mutantheart is like playing Simon Says; Mutantheart will say an Emotion, and all party members must change into that Emotion. If they don’t, Mutantheart will instantly KO them. That’s why items like Poetry Books, Air Horns, and Sparklers are essential for this battle.

Minor Imperfection

Average Percentage: 4.0%
Missable?: Yes

To earn this achievement, you’ll have to defeat Perfectheart. This one is the most brutal battle of the game; nonetheless, at this point, you should have more than enough resources to win.

First, do some level grinding. Level 50 is ideal for this battle. Also, go to the Lost Library and get all the exclusive skills by defeating all the Somethings. You should have Red Hands as well.
Buy Whole Chickens (In Orange Oasis) and Melon Smoothies (In the Mailbox at Last Resort). You’ll need them.

Omori Achievements Guide: FAQs

Question: Is Omori a Challenging Game to Start Grinding Achievements?

Answer: Yes, it is. But all its difficulty comes from knowing what to do and where to go in the exact moments. I recommend Omori to someone who likes to grind achievements and wants a big challenge that will take a lot of time.

Question: Which is the most Complex Achievement of Omori?

Answer: If we discard the boss fight-related ones because their difficulty comes from beating a demanding boss, I would say Foes Filed!

Question: Which is the Hardest Real World Achievement of Omori?

Answer: Universally Loved. It’s like Foes Filed! as it forces you to explore Faraway Town and complete all the quests there. It just takes a lot of time!

Conclusion

Omori is an excellent game with some of the funniest and most original achievements ever. It was such a pleasure to play this game. If you made this long journey alongside me, I hope you enjoyed it, and let me tell you, this game is pretty tricky in terms of achievements. So, yeah, I’m proud of you.

But if you are still considering playing Omori and getting all the achievements, I can’t do much more than wish you good luck. You’ll be here for a long while.
