Death Road to Canada is a fun indie zombie version of oregon trail

Enter the Gungeon is a bullet hell roguelike i really like, the enemies are all bullets and guns, and there is a bunch of diferent guns, its fun

Katana Zero is one of my favorite indie games, its an action-platformer about a dude with the ability to slow down time, also the free DLC is totally coming this year i have faith

Shovel Knight is the classic indie platformer its very good

Terraria is a fun 2d minecraft with rpg elements

Nubby’s Number Factory is a really fun and chill game

Also i havent play it but Starsector, is a 2d game about managing a Spaceship (or even fleet) and dealing with trade, exploration and battles, seems pretty fun its like the Real Time Strategy version of FTL, its not on steam plus its still in development but it looks pretty finished
