I love the concept! My only note is that the game page says it's right-click to shoot, but for me, it was releasing left-click that caused my ship to shoot. It would have felt better if it shot on mouse down instead of on mouse up.
HAHA I'm so sorry, I 'm so bad with left/right stuff Got a friend of mine to playtest at the very last minute and he told me about the mistake, but it was already too late to fix it :(
