I think I’ve seen at least two other topics about people looking for good (free) games.
Some other stuff is:
- Frog Fractions
- 100 [theme] Cats (a series of games on steam, also a lot of similar games some of which are paid)
- Swallow the Sea (I heard that Perfect Vermin from the same dev is also good (I like their games))
- Haven’t played this, but Baldi’s Basics is free on steam so I guess that’s something
