All of the compulsory levels in this game are self-contained, but if you attempt the bonus challenges then you'll need to plan ahead. To help with planning, this page will contain a screenshot of each level. Some of the challenges in this game are:

• Bring all 3 trophies to the end
  
• Complete the game without using the Revert ability
• Complete the game with the fewest number of snapshots
  

If you have the ability to merge, the blue door will be blocked.

One of the boxes contains a blue key, the other contains a green key.

You can simply walk past Basil, but if you're interested you can check out all the dialogue that come from merging and reverting mid-conversation.

The shop will sell you a hat if you have a coin. There are 3 hats you can buy.

One of the boxes contains a blue key, the other contains a green key.

The green box contains a red key.

If you have the ability to revert, the green door will be blocked.

If you have the ability to revert, the red door will be blocked.

Each character only appears at the end if you completed their challenge:

• Take at least 8 snapshots with Liv 
  
• Take at most 40 snapshots with Pluto 
• Buy a hat and give it to Pearl
• Beat Basil at one of his games

I hope this page helped you find loopholes and shortcuts in the game. Good luck!
