The sprites are all very cute. The keyboard controls are a bit uncomfortable at first. I liked you can choose 3 weapons. The sprite animation of the alien shooter, aiming with one of his eyes closed, nice. I can see that there were more and more enemies the further the level, but when I realized I can just ignore them, I ran past all of the enemies in later levels, which turns this action game into a weird enemy dodging platformer, which I must say I quite enjoyed it XD
