actually, we didn't have enough time to implement it (we just, and I mean just finished the global game jam, during which we made it). also, the music bug was actually found when you use the door then go back (it loads a second audio manager, I guess?). it was one line of code, but we already compiled the stuff, and we had too little time to redo all for tweaking a single line of code. that's just not something you can afford to do in a jam ^^. But I believe the development should continue for a while, if you're interested (can't promise it because I didn't code it, though, but it seems that's where we're headed). And of course, thanks for checking the game out ^^
