The best answer I can give is to try playing in fullscreen. That was a really weird bug in production that always seemed to stop in fullscreen—but we never figured it out. If Sparky still gives up, I'm so sorry it doesn't work!
I'll admit, it took me a while to figure out you could double jump, but once I learned that, the game was a lot of fun. The cheats are a nice little addon once you get far enough. Cool concept!
