Since the new version of Ren'Py was released today with Ren'Py Web Beta, I tested it out and uploaded it. I couldn't get it working in Chrome or Opera, but it works great in Firefox.

The music stuttered a few times, and writing of the tab-separated file for the Gallery doesn't work at all. The Gallery just shows a couple of test runs I did; it doesn't update when you get a good ending. But the game is quite playable. Loading, saving, sound, everything works except for the Gallery.
