Devil's Garage

Elder Scrolls blade was such a fun game! On the note of playing a smaller game Motherload is a surprisingly fun flash game where you dig for resources on an alien planet. The game is easy to learn but difficult to master. You get to experiment with different upgrades to find the best build for your playstyle. The levels are procedurally generated so it’s my go-to fall back game once a blue moon. Enjoy!

It struggles a bit on the late game I have not played around with the FPS limiter setting, but from what I hear that helps

Vampire Survivors is such a blast on steam deck!
