Ok I re-read the game jam rules and I completely screwed up, one mouse button with the movement couldn't count, so, i'm sorry if you have lost your time playing a game that didn't respect the main rule of this jam.
Well, no big deal =) but indeed it's a good thing to remember for next year, hehe. Or for december if you want to take part to the 2 buttons jam!! (same spirit, twice the number of buttons ;))
