I think the idea is genious.
You should make everything just look generally tidier because some parts (menu, passwords etc.) look a little messy and not nice.

Well...

Things to improve on: Some sounds,be it music, voices, background playground noises, or just a death scream when you die.
Maybe some proper animation when the guys take you down, instead of just 'bump', 'argh, I am dead'.

Other than that, it's brittish bull dogs! What's not to like?

Hammerypart says: I think you could do well, this idea was pretty new, y'know, kinda fresh. I'll root for you, if you follow the advice people give you. Cya 'round!

Oh, unless the advice is something like 'go die in a fire' don't follow that advice.
