Fun Game
Very cute; the graphics are nothing complex but it suits the game.
I didn't find it terribly difficult until I got to the giant jelly fish. I saw that I was losing more health than I was doing damage to the boss. Also, I found some difficulty in dodging it's attacks; maybe it's because the range is so close that I didn't have enough time to move out of the way. In relation to that, I find the movement a little slow even if you do hold down the shift key.
What's up with the mini jellyfish? I found some entertainment in shooting it but nothing seems to happen to it... Is it just there for fun? :P
Otherwise, good game.
