Fun
-I found this game to be rather enjoyable even though it was one of the simplest shooters i've ever played. Having a start screen with control instructions is helpful even though I was able to figure out the controls by trial and error pretty easily. Cute little cat enemies that shot pencils and some challenging but not too difficult boss enemies. Not bad for a first game.
-Only flaws I found were that you get full health regeneration too often and it makes the game insanely easy since all you have to do is spam the screen and you'll get a health powerup before you run out of health. Few tweaks and it should put some difficulty into the game.
