There are two gates that are closed and blocking the path to the starite. You need to get the starite close to these gates without destroying it.

1. Put an INDESTRUCIBLE BRIDGE on top of the middle spikes. Give Maxwell WINGS. Trip the black or the white wire. Fly up and get the starite.
2. Put an IMMORTAL TABLE on top of the middle spikes. Give Maxwell a JETPACK. Trip the black or the white wire. Fly up and get the starite.
3. Put an INVINCIBLE GATE (WOOD) on top of the middle spikes. Make sure that it falls into a horizontal position, and make sure that it is on top of the middle spikes after that. Give Maxwell a WINGED BEARD and fly up to the starite.
