There is no platform in the middle of the water — how do I cross?

Continue right from the left platform edge. The potato floats at water level; do not mistake the absence of a solid floor for a dead end.

Is the door visible at the start the final exit?

The door position shifts during the crossing. Float all the way to the right bank first, then enter the final door area.

Float right across the water from the left platform, climb onto the right bank, and enter the door area.

Layout: The potato starts on a left elevated platform. Another platform sits on the right, and continuous water fills the entire gap between them. The arched door is in the right-side door area.
Goal: Float across the water to the far-right bank, climb up, and enter the arched door to trigger VICTORY.
Opening: Walk right to the edge of the left platform and continue moving right to drop onto the water surface and begin floating.
Danger Zone: There is no intermediate landing across the water. Turning back, jumping early, or stopping mid-water when a door shadow shifts will break the crossing route.
Mechanics: Continuing rightward from the left bank causes the character to float at water level. The door shifts position during the crossing, so use the final right-bank landing as the route signal.

Hold right from the left bank and do not stop for the brief door shadow that appears below the water surface.
Confirm the potato has climbed onto the rightmost platform before moving into the door area.
If the board feels stuck, look for the color with the cleanest path and use that to regain space.

Hold right from the left elevated platform and walk to its far-right edge.
Continue right off the platform so the potato drops to the water surface and begins floating.
Maintain rightward movement across the entire water stretch without turning back or stopping mid-water.
Reach the right-side platform and continue right into the arched door area.
Wait for the VICTORY screen to confirm Level 41 is complete.

Jumping early at the left platform edge, missing the water-float route.
Stopping mid-water when the door appears at a low position instead of continuing right to the bank.
Turning back during the crossing, losing the continuous left-to-right momentum.
