The theme is: Weird! Duh.
I'll take a look at the top 10 submissions and declare a winner, although my opinion on games is only my opinion and may be entirely different from other opinions, so just be proud of your overall rating. But do check out the winner once they are announced! Obviously, nothing that can be seen as not child friendly or rude overall (racism, transphobic, etc). Any assets can be used, but the gamee has to be made in the one week. You can still brainstorm before, obviously! Also, the game has to be free to play, at least until June. Any engine is allowed.
