left and right arrow keys to move space to shoot and you need to shoot the aliens :) if i get 50 views i'll update it, then for 100, 200, 300, 500, 750, 1000, and each thousandth view after that, although it probably won't get that far. but do heart/favourite if you enjoy. i may be adding mobile controls later on tho. my high score is 3150, see if you can beat that.
i got a lot of inspiration from space invaders but didn't like the bunkers so i got rid of them, i also added a boss :D
