Slay the Spire is good if you haven't seen that yet.

If you're looking for singleplayer games;
Celeste, Slay The Spire, Pixel Piracy, and my personal favourite LISA. If you were to pick up any games from this list I'd definitely go with LISA.

Moon Hunters is also a really fun game and can be played with up to four friends. If you need more recommendations or a link to those games store pages just send me a pm on discord
