There are three achievements that are related to the tutorial, and two of them are missable. If you miss them you can start on a new save file and you will be put through the tutorial again.

Simply die during the tutorial. Fall into the first pit you see and it will unlock.

During the tutorial there will be a duck teaching you how to play. Near the end of the tutorial while he's teaching you how to swim he will be sitting on the surface of the water. Simply jump on top of him until he says "Alo Boizaum!" and the achievement is yours.

Unlocked for completing the tutorial, impossible to miss.

All of these are unmissable.

Complete the forest world.


Complete the lava world.


Complete the snow world.


Complete the toy world.


Defeat the final boss.

See "Where's The Door?".

Acquire all 20 keys in the game, there's one in each level of the four main worlds. Once you collect a key you will keep it even if you die or quit the level. There's a video guide available below.


After collecting all 20 keys you will be able to access the nostalgia world that is to the right of the final level on the level select. Each level has a unique gimmick that doesn't exist anywhere else in the game. Complete all 5 levels for the achievement.

Collect all the eggs in the game. All levels have eggs to collect except the first nostalgia world level. None of the eggs are really hidden, but you can know when you have all the eggs in a level when the bar with the eggs turns yellow as shown below.


Die 500 times. You can simply idle the second nostalgia world level, as the level starts with a boulder chasing you.

Beat the game (the four main worlds) without dying. This is the tough one. I recommend you practice each world on a different save before attempting to beat it on your no death run. In the level select you can see your total number of deaths at the top of the screen.
