Thank you for your feedback! I would very much like to see the gameplay and the bug. I probably won't be able to sit down with the code until Monday, so no rush. It has been very hard to get any feedback on the Android version, so I'm very grateful for your reply.

Ah, it all makes sense now. It was a clipping glitch and you fell through the floor. I've seen it once before, oddly enough on the same level, but haven't been able to replicate it myself (I spent much time running at walls). It's going to be hard for me to fix it, but I'm relieved that the game didn't hard crash (phew!) and I now know that the glitch is in my collision code.
Thanks tons! I've downloaded the video, it was fun to watch, but also might help with a good place to find a possible collision error.
