Pretty Good.
Pretty Addicting. I had quite a bit of fun. I Agree that it's a tad bit on the simple side, though. Give me a life bar, more powerups such as healing and temporary unlimited super power, and maybe a bigger playing field wth one or two new enemies, and I would probly give a ten. Other than that, really nice attempt, I really enjoyed managing the power bar and making it longer. I'm waiting for more!
