I really like the core concept, it took me a bit to figure out how to successfully pull the moves off. I think there was a bug at some point, there was a locked door that gong on the button wouldn't let me through, but I still enjoyed figuring out the permutations of moves to change sides before that. Also, the line "I wasn't a gambling man / but he was / so I became a gambling man" is pretty great. Good job!
