4D SLICE LAB
The dungeon floor is a 3D volume (x east, y north, z the third floor axis). The three
panels are thin slices through you: XY, XZ, YZ. Moving in the active
panel drives its two axes; the third only changes when you move in another panel.
Collect the 5 gems. They are
deliberately hidden 1–2 layers off the obvious slices — use the render-mode lab
below to make the invisible bulk readable. A harmless drone
roams the volume so you can judge how well each mode tracks moving off-slice objects.
