It's a sidescrolling rogue-like that plays a bit like the old metroidvania era Castlevania games (and honestly I'd say it plays better than those). I'm gonna be streaming it later, so you can always take a peek at that to see what it's like.
Games like Mass Effect are nice, but put a rogue-like that plays like Castlevania in front of me and my true allegiance to really fucking hard sidescrollers comes back to the surface.
