Move the yellow ball along the wires from the red dot to the green one. Use the arrow keys to move within a layer, and I/O (in/out) to move between layers. The currently available keys are marked on the maze, at the points they would lead to. Move the mouse to change the viewing angle. Mazes are randomly generated, and each time you win, you get a more complex maze. Press R to return to the red dot.
The isometric 3D engine is based on https://scratch.mit.edu/projects/25977969/ by @uiopscratch327 (thanks). The maze generator is similar to the one at https://scratch.mit.edu/projects/97085616/ only instead of a "walls" list (saying where you *can't* go) it has a "wires" one (saying where you *can*): 1 - a wire to the next column (right arrow) 2 - a wire to the next row (up arrow) 4 - a wire to the next layer (O) Update: I've "rigged" wire selection to have a smaller chance of picking an in/out (4) wire because they were clattering the view. This is where I do floor((pick random 0-8)/4). Chances of getting 2 are 1/9, while 0 and 1 have a 4/9 chance each. I hope it's easier to play now.
