Nice work. I would recommend working on the "game feel". So when you kill an enemy maybe the screen shakes and a loud sound is played. details like that go a long way. also, maybe try a system where you shoot where you click on the screen. I think that would give more control to the player. If you could check out my game that would be awesome. Here's the link: https://itch.io/jam/blackthornprod-game-jam-1/rate/319010
