Crypt of the Necrodancer - A bit confusing at first but seems like a lot of fun. Custom songs option? Nice.
Environmental station Alpha - Seems like an atmospheric metroidvania. Having just finished Symphony of the Night, this will not be played in a while.
Hyper Light Drifter - Beautiful, need to have a day off to really dive into it.
Tower 57 - Really great in 2 co-op. If you're into Chaos Engine, this should do the trick.
Sonic Mania - An amazing overhaul. A lot more responsive controls.
Will probably also buy S.T.A.L.K.E.R: Shadow of Chernobyl and Bloodstained: Curse of the Moon at some point.
