Thanks :)
graphics and animation could be improved, i was planing to add a layer of hand animated gears(like those in the great mouse detective) but animation especially hand drawn animation takes a lot of time to create maybe with more time it could look much better, the side wall was actually going to have window with lights coming it, at the end i add a perspective effect which make it a bit 3d. and the character animation can be improved in many ways like with much better cropping.
i was actually learning box2d while making this game, also i didn't know the best way to make plat former controls. I'll try to make them better :)
I realized that for the developer its hard to fin-tune the controls because he had played it so many time that he get habitual to those controls so it's hard to know how bad controls really are.
