Very fun game. You might get more replayability if the fire rate starts slower and gradually gets faster. That way the challenge builds up over time instead of starting off at full difficulty. Other than that, very good job being able to do this in only two hours. Well done :D

This is pretty cool. And it gets hard very fast. My highscore is 22. I think the cover image could've been choosen more wisely in order to attract more people, though ;) What do the yellow things mean, that are spawned from the white thing on the top?
