Glass Planet — walk the outside and the inside together

How to play
You can press across, upright, or depth only when that seam is open on both shells. That one step moves the outside and the inside together. Walking onto the exit cells wins; starting on an exit would not. A cracked cell or an inner void loses, as does step 8. The view button does not change the board.
Origin & history
Glass Planet is an original OIYO puzzle that moves two people on opposite sides of a sphere with one input. Four boards were checked by hand; a seed picks one. It uses no map or audio from another game.
FAQ
Does the same seed always build the same planet?
Yes. The seed picks one of four boards that were checked ahead of time. The board is not reshuffled every frame, so a shared address is the same puzzle.
