An alright game. I think co-op is the best way to go here--that's how I played it. The level design and enemies could be a bit generic (and sometimes annoying), and it definitely suffers from a bit of padding; still, it isn't trying to be anything more than a cute Castlevania homage/parody. Shinobu and Maya are fun to play as but don't reach their full potential until their full movesets are unlocked. My friend and I both agreed if they changed some stuff about this game structurally, it would be a bit better. I definitely had more fun once we could do everything. Play if you want a short, but decent couple of hours of action-platforming with a friend.
