Ill give you some more fast paced than the other recommendations. Games that really suck me in for hours zoned out.

Nova Drift helped me zone out for hours and is good on the steam deck. It’s an Asteroids style game. It’s just shoot up fun with more upgrades the longer you survive.

Crab Champions is a silly shooter with the same basic recipe. Survive, get upgrades. It’s silly though because you are a crab, fighting other crabs. It’s fun.

Comedy option - Getting Over It with Bennett Foddy. Face your life frustrations head on and play a game designed to make you angry.
