It is actually possible to do that; because whenever someone downloads a game they have full access to the images created and used in that program.
As far as online presence is concerned, the focus is fuzearena, the Fuze forum (I think there is a link to that in most cases, but i could be wrong)
As I have the main Fuze app, I've played a few of these already - and I might be biased, but the selection included here is quite awesome in my opinion!
My personal recommendation for anyone picking this up is 'Super Laser Blast'. It's super addictive and perfectly suitable for passing your time...
