Tool a screenshot inside one of the 3d mazes in that online game link I posted:
The black transparent glassy lines means you can go through, while the walls with 9 square holes in them are the dead ends/walls. (Sliding your finger on the lower left of the screen moves you and swiping on the lower right changes your direction)
No never heard of it, just read the plot summary and it looks cool though.
The problem with the coding I feel like would be all the extra parameters, it has to generate the vertical pathways randomly between levels, while not opening up redundant routes leading to the correct route in the process. Like if your correct path you decided on involved levels 2, 5, 4, 7, and 9, the program would have to make sure no combination of paths involving 1, 6, 2, 1, 5, and 9 also accomplishes the same thing. Even false paths connecting to the correct destination level, would have to make sure they arrive at dead ends on that destination level, while the correct vertical path arriving there, doesn't arrive at a dead end. Can't even imagine the complexity to be honest. We live in a 3d space but things get absurdly complicated adding the 3rd dimension onto common games lol
