Wow, nice game. It's really fun. And good that you put in a CPU enemy, as I don't have someone to locally play this with right now. I can imagine this getting pretty intense with a human opponent.
The collision with the ball and getting stunned felt kind of janky at times, but overall I liked the mechanic of being punished when missing the deflect. Also stunning the enemy to hit it in the goal felt very nice.
Cool entry!
