Some stuff @Auroriax recommends. I generally like puzzles, rhythm games, and walking simulators the most, but this list is pretty much a mix of everything. Enjoy!
Here are some other guidelines for this list:
- Only one or two games per creator—if there's more good stuff I link to the developer's page or related games.
- If a commercial game is on Steam, I'll link to it for your convenience. (Try to support your favorite creators via itch.io, though—they'll get a bigger share if you do so!)
- No 18+ stuff. (Some of it comes close, though, although these games list content warnings on their site pages.)
