It could use some kind of indication of where to go. Perhaps a number indicating the depth of the branch you're entering or the breadth of the tree you're in right now. Right now I feel like I don't know what I'm doing and there's no real way to master this game.
FYI your source version has a line "import pattern" that fails because there's pattern module. I ran the Linux version fine, though. Kind of a cool idea but the pacing is a bit slow to really be fun.
I think it's a bit of a cop out to tell your audience to put on other music while they play. That being said, I played without music, and the tacking of my mechanical keyboard was not relaxing.
Cool concept though, but it needs work.
