cool take on the theme! I really dig this idea! It took me a while to hit enemy, even when punched, and it was made even more hard when you had to rebound the bullets against the correct color (which sometimes were hard to tell which color was which). I would suggest making the stun time a tad longer and removing the color aspect, or at least hold off on that until later waves to increase difficulty. Overall, good job!
I'd appreciate it if you could play/rate my game as well! :)
