There is no double jump, no, we decided to get rid of it in favor of more interesting movement options. You can activate infinite jumps in the Debug Menu once you reach the end of the demo, though! Just be warned that they won't save after you exit the game, like other debug mode options.
yea thats actualy what made me think there was a double jump cuss when i reached the debug level the infinite double jump option had me thinking i missed something , HAHA so ive been on a wild goose chase , no worries i totaly agree with the power up setup you have now , even when i finished the game still so fun just to mess around .
