It's cool, but it needs a tutorial or manual of some sort. It's get's really easy really fast and killing the enemies doesn't feel satisfying, this game would really benefit from different weapons and enemies, as it stands all enemies feel the same. I really like the sounds. The upgrades of the ship in the planets need more variety too, every battle feels the same. Also everytime I kill an asteroid the game lags. Overall pretty good looking game and cool idea but needs some work.
