This was a pretty fun little game. The aesthetics were pretty good. The game-play is promising, but like others have said, it's a little difficult to aim the shots accurately, but it was still pretty fun to just dodge the shots from the enemies.
There are a couple of ways to improve the game-play. You could maybe make it in first person, or you could move the camera to a better position so the player isn't in the way. Making the projectiles shoot towards the, like others have suggested, would have also been a nice touch.
Anyway, I had fun playing your game, and I wish you good luck in future jams :)
