Which platform should I use first in Level 23?

Start on the upper-left ledge, then jump down and right to the central platform before continuing the descent.

Is the white balloon-like object required?

No. It appears as the platform arrangement adjusts; the objective is to preserve the platform route to the lower-right door.

Mr Potato level guide

medium

Descend through the adjustable platform route from the tall left ledge to the lower-right door.

Layout: A tall white pillar supports a narrow upper platform on the left, where Mr Potato starts. A large white block occupies the upper right, and several narrow platforms span the middle and lower route toward the lower-right door.
Goal: Use the changing platform arrangement to descend from the upper-left ledge and enter the door on the lower-right ledge.
Opening: Move right along the upper ledge, then jump down and right to the central platform instead of aiming for the door in one jump.
Danger Zone: The gaps below the starting ledge and around the large upper-right block can send the potato off the route; re-center after each landing before the next descent.
Mechanics: The platforms adjust during traversal and form a descending staircase. The observed route uses the upper-left ledge, central platform, lower middle platform, and lower-right approach in that order.

Treat the level as a controlled descent: take one platform at a time and correct the horizontal position after every landing.
The small white balloon-like effect is part of the platform adjustment, not a collectible that needs to be chased.
If the board feels stuck, look for the color with the cleanest path and use that to regain space.

From the tall left pillar, walk right across the narrow upper platform.
Jump down and right onto the central floating platform below the upper route.
After the platform arrangement adjusts, use the next middle platform rather than trying to land on the large upper-right block.
Continue down and right across the lower platforms, correcting the potato's horizontal position after each landing.
Reach the far-right lower ledge and enter the door to complete the level.

Aiming directly from the starting ledge to the lower-right door skips the central landing and causes the potato to fall away from the route.
Chasing the white balloon-like adjustment effect treats a visual route cue as a collectible and pulls the potato off the intended platforms.
