By the way I have a better idea for the button positions. (SPOILERS Y'ALL!!!) There should be two buttons where you want the shortcuts to be, three in each of the secret rooms, and then five in the RUST labyrinth. The place where Fleshy is is hardly a labyrinth, and besides, new players who aren't used to the map are a lot more likely to come across the buttons too early. They should also only appear if you've already finished Albert in a previous run and completed the Math Level.
