I followed your progress on Discord and have to say that good job on this one! Although I am not the biggest fan of asteroids style games, but this was quite well done! :) One mechanic I would love to see would be a over heating system, so that you couldn't just keep pressing the mouse button for the whole game. Adding that would obviously mean that you would have to probably slow the enemies down a bit to make it more balanced again. But just a suggestion, good job on this game! :)
