It's a nice little time killer. The game gets a little stale after a while, though. I think making the difficulty ramp up at all would be nice. Also, the enemies attack so slowly, and deal no damage, that I could literally stand still and not die.
Thanks for the feedback!!
You are right, I did put the damage very low for the player. I wanted to add some more enemies and waves system but was too late.
I actually made this in two days not three.
