Low Oxygen Puzzle and key guide

The keys are missable collectibles/achievements that unlock turbo mode if the game is finished by collecting all of them.

Video guide

This video doesn't cover a few of the puzzles that serve as introduction to the game's mechanics.

Key locations

At the start of the game, go left, hold E to carry the box over the door opening trigger then continue left to find the yellow key



Start the moving platform and jump under the fourth ceiling lamp to find the red key



Jump up the ladders to find the blue key



Drop down and hold left to find the white key



Don't go in the rocket and jump to the right to find the black key
Jump a few tiles earlier to catch the ladders, but don't worry if you miss it, a checkpoint is near.

Don't jump at the last tile of the platform for the Black Key. Jump ~5 tile early otherwise you will thread through the ladders.

Yes, you need to collect all the keys in one go.

btw for the turbo mode, do you need to collect all the keys in one go to unlock it? bcoz I collected all the keys already, just not all in one playthrough, but saw no option in the main menu after I got the last key

Tysm! Didn't know that the red key was in that wide area with the platform, like a pitfall, than in that small pit area a few puzzles further

If you collected them all, you can start a new game with turbo mode which makes the game run twice as fast.
