You should also rate the game on how good it is.
I like the Game&Watch idea, very nostalgic. As someone else said, I want to press the screen and see all the sprites show up (possible new feature? Sexy.)
You did what you wanted very well, but the game itself.. is... lacking.
With the medium you have, it was made well, but I believe there was another real G&W game much like this.
In short: Good premise, sub-par game.
(I loved the sounds, btw :D)
