Not a jam game
But it fits the theme so I'm sharing it anyway. This is my first steam game that I coincidentally happened to release the demo for a few hours before the jam started. It's a game about building and fighting creatures made of cells.

I was thinking about making a spinoff game using the same engine and similar mechanics for the jam, but it felt like it was reusing too much work to be in the spirit of ludum dare. I don't have the energy to make something completely new when I was already in crunch mode for a few days, so I sadly won't be submitting anything this time.
Good luck to everyone participating!
