I really like the graphics and titlescreen.
The gameplay is a little bit weird to figure out. It would be nice to get a way of fighting back for additional points as I've never been able to live for more than twenty seconds.
The hitboxes ar also a little bit off. Sometimes I fly right through a missile without dieing and others I die in an open field.
To concude this I'd say that you have a game with a lot of potential that, if you would've had more time, could be something very entertaining and addictive.
