maybe instead of arrow keys use the mouse to get through, more levels as well. the game was slow and frustrating since i hit 8 rocks (i think that was all of them in the level). No idea what score was calculated on as well.
Looks really cool, but not much I could do by way of user input. Too many enemies and too frantic, so it would end up being just me with the bots at the bottom spamming back and forth the bullets at the top while using the laser cannons all the time. ended with a score of 2.3 million. 3/5
