The game, despite being only a demo, presents already a solid gameplay with an innovative twist. Mechanics are simple to understand but hard to master and classic mode is very funny with the interesting addition of the variants that happen after every goal (pong made me smile).
The polished and colorful graphics, combined with the two-keys-are-enough-to-play gameplay would make, I think, the perfect android casual game.
I hope you will consider porting the game (or a simplified version of it) on android (obviously it would need online multiplayer).
Thanks for your attention.
5/5 for the demo!
