I enjoyed the humorous story very, very much :) "these peculiar non-cheese structures!?" :D Juni sounds very appalled at the fact they're not cheese!
I wish the level was a bit longer, or at least some equally nice explanation of the stars etc. was given :)
Not much to add to the Jack's post concerning the technical details (actually, I never noticed the voids since I never double jumped :crazy:). Taking away the double jump is accomplished when you set the starting position in the editor. Click SetStarPos and you'll see a table of powerups and keys light up, de-select the double jump, click on where you want the starting position to be, and that should do it.
