Which platform should I jump to first in Level 9?

Jump to the lower floating platform first, then to the higher one. The two landings break the route into manageable jumps.

What do I do when the door flies to the top?

Stay on the higher platform and wait. The door descends with the balloons — jump right only when it returns to a reachable height.

Climb from the low platform to the high platform in two jumps, wait for the balloon door to descend, then jump to the exit.

Layout: A low starting platform leads to a gap. Above the gap are two floating platforms at different heights — a lower one and a higher one to the right. A balloon-carried door floats at the far right.
Goal: Reach the higher floating platform and jump to the door when it descends to a reachable height.
Opening: Jump from the starting platform to the lower floating platform first.
Danger Zone: No ground exists between the platforms or below the door. Jumping toward the door while it is elevated leaves no landing point.
Mechanics: The door is lifted by multiple balloons and moves vertically. Its height changes over time — the player must wait on the higher platform for the door to return to jumping range.

First jump targets only the lower platform; second jump goes to the higher platform.
When the door is high, stay on the higher platform rather than chasing it.
Jump right from the higher platform only after the door descends to a reachable level.

Jump right from the starting platform and land on the lower floating platform.
Adjust position on the lower platform, then jump up-right to the higher floating platform.
When the door is carried high by balloons, hold position on the higher platform.
Wait for the door to descend to a jumpable height on the right.
Jump right from the higher platform toward the door and enter it to trigger victory.

Jumping from the starting platform directly toward the door, skipping the necessary floating platforms.
Landing on the lower platform and immediately jumping at the door without first reaching the higher platform.
Chasing the door upward when it is elevated, falling into the gap between platforms.
