Nice game! Had a lot of fun with this one. I'd say the bullets being able to hit the player is currently a little too punishing. I found myself being way too careful with my bullets instead of utilising the reflection mechanic to take out slimes. I'm thinking possibly a lifetime limit on the bullets could be a nice addition, so that they aren't bouncing around forever until they hit something. This was especially an issue when the round was over and I was trying to dodge the bullets and choose an upgrade at the same time. Otherwise, I love the game's concept and gameplay, I see a lot of potential in it. The art style is also super clean and consistent throughout the game. Great submission!
