This game is not for the weak of spirit. This game will challenge you and make you a better person. Stop paying your life coach and start paying $0 for this instead. I heard somewhere that Bruce Lee used to play an antiquated version of this game to prep himself mentally before fighting a hundred extras. If you're ever caught in a bad part of town and you need some instant street cred to get you through, just let them know you made it to stage 3 in this game.
On a more serious note, I thought the navigational method was unique but I thought the keymapping felt a little weird. I think using the WASD cluster instead of the arrows might make more sense since you can still reach the shift and space with your other fingers.
