This was a blast to play, I feel like everything was fleshed out nicely, and the way time slows down when you are about to hit someone is a super cool feature. My only criticism is that its very hard to distinguish the CPU and player apart, because they look alike. My suggestion would be to change the color of either the Player or the CPU. This would help alike.
Apart form that, I thought your game was really good and I really loved your art style! Congrats! :)
