Little Pilot

Hints and tips:
1) Check for the grass blocks. There are only three types of blocks that you should tap:
• grass blocks
• metal blocks
• the ball

2) Don't tap any block during B's autopilot especially on the topmost part of the level.

3) Look for the shortest distance possible between levels to make it easier for you to drag the lift and for B to perform the autopilot.

Tricks/effects required to finish the level as intended:
1) autopilot
2) claustrophobia

Spoiler: Intended solution>

1) Getting the first ball - lift the elevator up to the 3rd floor. Tap the grass block and drag it up to the rooftop. Wait for B to nudge the ball and go back to the lift.

2) Once the ball is in place, you will be able to tap it before dragging the lift upwards until it reaches the rooftop. At this point, B will perform the final autopilot required to finish the level as intended.
