Ok, so there is a bit of a problem :/
The lastest build I could find of this is missing a few polishing things.
The levels are all there & I think I fixed your loading bug, but its missing title screens and stuff like that :/
Its the only thing I can send you right now, but ill keep digging for the master build. I know I have it somewhere....
I should really add a sticker on this game, saying that it has a few problems & that i can find the build anymore!
What platform are you on?
Or do you want a hmtl5 version?
cheers,
josh
