I would give it 5 stars but it is extremely rough around the edges and the gameplay needs work to make it flow better. I think different weapons should have special abilities (burn, freeze, poison etc.) Besides that it is very good and easy to progress through. A joystick instead of arrows would be nice too. I would definitely check it out if I were you.
