Doesn't quite meet the requirements. But it is a very playable and decent platformer that exists between classic Mario and Kaizo. The challenge scales briskly. Worth trying if platformers are for you.

A good tower defense with spooky NES art and retrowave. Levels are well designed and allow for multiple good setups. Tech tree is strict so plan well for more than just the next level.

Space RPG with a lot of ways to play. A weak recommend since while it allows a lot of flexibility of playstyle there isn't a lot of depth to any of it. Only if you like space and need a time waster.

Turn based stealth. Think Metal Gear AC!D without cards. Limited story, mostly a race to gather resources before the final mission jumps out at you. Ran well on my setup but be careful on the low end.

It's a linear scenario based tactical RPG. If you liked modern XCOM but wished it could run on actual garbage this is a decent choice.

It's like my job if my scripts did anything useful and were actually tested for correctness before deploying and the dystopia I lived it was more neon. PRINT THE MANUAL.

Just a good ol' puzzle platformer about a goat. I still need to play the sequel, which is also on linux.

Make your god and take your throne! Get a group and set up your play by email game on llamaserver. Agartha is best because of the caecilians. DOM5 DOM5 DOM5 DOM5 DOM5 DOM5 DOM5 DOM5 DOM5 DOM5 DOM5

Darkest Dungeon but in space. I like the setting and unique mapping mechanics but do not iron man it as character death is significantly more punishing and less fun than DD.

Dungeon crawling RPG in a lovecraftian gothic horror world. Your characters will either die or go crazy. A playthrough will last forever. It's surprisingly resource intensive be careful on the low end
