i've found a bug, when u lunch and minimalize webrowser and during fly do something else u will fly higher or further depends on game mode, seems speed lost is smaller, for example in story mode with hero costume lvl 2 and nuclear reactor lvl 1 i reach around 180k altitude in "normal" flight around 50k less
For me its best game on kongregate. Nice and funny graphic, many upgrades and equipment, interesting maps really good job :) Only thing that gems should be recived more randomly i always get emerald -_- :) but despite of this i play this game with pleasure :) greetings from Poland :)

 "Hero Simulator"){kind=icon}
 "Crazy Fairies"){kind=icon}
Should be nothing more than leaving earth fast in a completed story mode. Maybe there's a bug but it seems to work for me.
