You only want new games cause there's a few older games too. I don't know if you'll be able to handle them since I don't know your setup, but it's always something you can look at to see.
Blasphemous, Broforce, Chasm, Dust: An Elysian Tail, Final Exam, Guacamelee 1 and 2, Hollow Knight *it's about 9 gigs though and you said you wanted a smaller file size, but this game is amazing and hard*, Rocket Birds, Rogue Legacy, Valdis Story, Volgar and if you like stuff like Flashback and Another World then look up The Way.
