How to solve puzzle 1501 in The Entropy Centre
Enter the room and you’ll notice a laser box nearby. Pick the box up and then put the laser box down so that it hits the first panel.

Afterward, place it on the conveyor and drop down to the floor below — but be careful not to touch the blue field. Go up the stairs to the switch and step on it until the laser hits the other panel.

Once it does, shoot it and freeze it. Use the jump pad to get up to the door that’s now open. Go through it and rewind the laser box until it’s hitting the first panel. The door will open, allowing you to grab the bridge box.
Take the bridge box and drop it down below. Press Q and stop rewinding so that the laser box falls on the ground as well. Pick them both up and move them toward the blue field, careful not to have either box touch it. Have the laser box point at the panel in the wall near the blue field.

Pick the bridge box up and put it on the conveyor. Next, pick up the laser box and aim it at the panel that opens the exit door. Then take the laser box and put it on the panel that activates the conveyor, before moving it back to the panel near the field to create a loop. Get on the conveyor and rewind the laser box to put it on the panel that moves the conveyor and ride it until it stops. Finally, place the bridge on the moved conveyor and aim it at the door to create a bridge, which you’ll walk on until you get to the door.

Once you’re at the door, rewind the laser box until it’s aiming at the door-opening panel. Finally, go through the door and you’ll be done with puzzle 1501 in The Entropy Centre.
