The best metroidvania I've played yet. Incredible music and visuals, absolutely love the graze and magic system, love the stop time mechanics, the different ways you can use your knives and weapons and how that combines with the time mechanics and oh my god the BOSSES. The boss rush in this game is easily the most fun I've had in any game with a boss rush.

EDIT 2/9/21: Played through this again for the Cirno boss fight they added. It's just as good as all the other fights, though I wish it was in the game when I first played it because with the amount of times I've played it wasn't as much of a challenge as I would like, but still incredibly fun. Anyway, this game still rocks and has some of my favorite bosses in any 2d game.
