tbh I didn't really enjoy the game, the concept and the intro are very cool, but all I did in the game was move up and spam the mouse to shoot, also picking up the green gem hurts the ears, especially if you pick many at one. another problem is there was no danger as I kept picking up more health than taking damage. to make it more interesting I would make the asteroids give less health, but also spawn a bit less of them. also lower the volume of picking up the green gems
