Hi! There is no specific theme, but you’re encouraged to take optional challenges:

• The game takes place underwater.
• The game is a dungeon crawler.
• You cannot control the character(s) directly.
• The game is about cats in space.
• There are no living beings in the game.

You can pick one, or you can pick more, or all of them at once (I try to implement all the 5 of them, but it is hard XD)
