Very nice, I'm impressed you made your own game engine, that's not an easy task. A darker outline for the bullets would be nice, so they can be seen on the yellow floor. Good controls and game play! Good Job!
Thank you! I wanted to add glow to bullets to solve that problem and make it look cool, but I ran out of time. Wish I thought of your solution. It's way simpler and I could've done it in time :D
