How does the game fit the theme?
You stack polyominoes(tetris-type pieces) with physics enabled, what could go wrong? well... probably nothing?

What code and assets did you not make from scratch during the jam (if any)?
I made everything except for the music which I got from "pixabay.com", specifically:
