You need to incorporate the Theme into your game in some way and before you submit it, you will need to write atleast 1 short sentence about how your game fits the Theme of the game jam. It's completely up to you how you interpret the theme. Feel free to be creative with it.

Theme: Machine of Doom

Bonus Challenges: Unlike the Theme, these are entirely optional. Feel free to do one, two, all of them or ignore them completely.

For this game jam, the optional challenges are the following three:

1 - Source of Corruption: The game is about a machine that corrupts the land and drains life out of it.

2 - Fueled By Life: The game features a scene where living beings are used as fuel or to power something.

3 - Pipe Puzzle: There's a puzzle in the game where the player has to direct the flow of some kind of liquid to a particular destination by manipulating pipes.
