This game is pretty fucking good. Dark, trippy and menacing.
They've only just released gameplay footage, and it's at GDC and PAX, but I've played it for the IGFs for the last couple of years (and it is up for an award this year).
This is excellent. It's not the same type of game as Beat Saber, as it has levels and progression instead of individual songs, but it still makes you feel like a badass when you nail sections. I've just finished level 4 of 9 and it's already pretty hard.
