Rimworld. Does have a native Linux port. It’s a colony simulator in space. 2D. It you have a lot of control over your colony, you can micro manage everything. I have over 1000 hours in the game.

I always take my glasses off before looking in mirrors. I’m more attractive when I’m slightly blurry.

Compressed air to start with. Rubbing alcohol and an old toothbrush for what remains after that.
