I agree there is a bug it seems about certain switches being un-flippable for some reason, or I didn't understand the rules. Check out my review at https://www.twitch.tv/scalphamission

The game challenges you to make the best moves and solve the puzzle in the minimum amount of moves, but when you make a move that is of no use to you, the game plays the "fail SFX" and does not allow you to do it. Anyway, thank you for sharing your feedback in your live stream. I appreciate it a lot.
