I like this game, you should have introduced the crystal feature a little later. It really makes this game stand out against all the other platformers. Should be a highlighted feature. :) I'm sure it'd make this game more popular.
there is a bug. When I flip a burger, they remain in mid-air. This really sucks, you can't use that particular space on the fryer anymore and it's a real eye sore. Patch? :P
