I'm not sure if I even should, but I normally play the game by loading the swf file in a browser directly, so I can fullscreen it easier than using the zoom things and so the browser doesn't have to render a page around the flash object which could be a performance penalty. It sure as hell was on FFR.
Anyway, I just tried to play the game that way, and the levels wouldn't load. Loaded up a sniffer to see why, and it turns out it's trying to load files in /game/files/game/files, which obviously don't exist. So the player is suddenly using relative paths for some files. Like the title says, it's not really a bug, just not very nice imo.
On a sort of related note, the game doesn't load at all when running it on the 3rdstyle.com domain. Could be a bit confusing for people who're going here for the first time after hearing about it.
