There are a lot of good things about this game. The soundtrack is great, it's challenging, and it has a solid foundation. However, I think you could make the death screen less abrupt and plain (maybe display a message like "Game over, you died!") and you could also make the game more interesting by adding a background and other obstacles.
Wasn't quite sure what was going. a little too chaotic for me. Very hard, especially later on. I would suggest less rocks, slow the bullets/increase the gaps between them a bit, and this could be a very fun game.
this game is fun but hard you could add some ground textures and make it so you can use wasd.
