Can I use the top of the moving block as a platform?

The verified route stays in the lower running lane; the block's underside is the dangerous surface and is lined with spikes.

Which door is the target?

Run from the left start to the arched door at the far right.

Run beneath the vertically moving spiked platform and keep moving right until the far-right door opens the route to victory.

Layout: A flat floor connects a left starting door to a right exit door. A long rectangular floating block spans the middle, with a continuous row of spikes on its underside.
Goal: Cross the hazard and enter the arched door at the far right.
Opening: Leave the left doorway and hold right along the ground, using the opening beneath the floating block as the running lane.
Danger Zone: When the block drops, its spiked underside becomes a low ceiling; a high jump at that moment collides with the spikes.
Mechanics: The central spiked platform moves vertically and changes the available clearance. The route is a timing run through the lower gap, not a climb onto the block.

Keep the potato moving right and stay on the floor whenever the spiked block is low.
Use only a short corrective jump in an open gap; never aim for the spiked underside.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

Leave the left starting door area and hold right across the flat floor.
Approach the central floating block while keeping the potato below its underside.
When the block rises, run through the open lower lane; use a short jump only if a correction is needed.
Continue right as the block changes height, avoiding any stop beneath the descending spikes.
Reach the far-right arched door and enter it to trigger VICTORY.

Jumping while the block is low sends the potato into the row of underside spikes.
Stopping in the middle of the lower lane lets the moving block close the clearance around the potato.
