where do you see either your life or how many lives you have? and what's the end objective? i mean, it seems that all you do is move around and keep firing. and it took me a few seconds to figure out how to play. i figured out movement by accident and it took a while to figure out how to fire. a little how to play thing would be quite a good idea. maybe add in a level system and definitely give the player some way to understand what everything means on screen and what they're supposed to do.
