Probably one of the best games I've ever played, absolutely worth $0.
Basically the only title I've replayed over and over again to get the special "good" ending.
A good bonus is that if you play, and get good at, this game - you can then move on to other, parry-based titles (like Sekiro) and they'll feel like a walk in the park.
The game is easy to start, but besting it at all will require you to replay some levels.
