In fact, this kind of games is highly recommeded to play with gamepad, but that "conversion" of keys I will do it at last. The priority now is the prototype works fine and feels good, faster and smooth.
I wouldnt consider this has a demo yet.
The mini bicycle idea come to me when I was watching an episode of the Simpsons (Homie the Clown). I forget to disable it on this version. Of course that will be in the game.
