How to solve puzzle 1504 in The Entropy Centre

First, grab the cube and turn it into a bridge cube with the purple field before placing it like you see in the image below. Then delete the rewinds with the ‘R key.’

Next, pick it up and turn it into a laser cube via the red field before shining the laser on the panel.

Then pick that up and go through the blue field to turn it into a jump cube before placing it here.

Finally, pick it up again and place it here:

Jump on the just-placed jump cube, and then rewind it to jump on it again. Rewind it once more so that it’s hitting the laser panel.

Finally, rewind it into the first place you placed the bridge cube right here:

Now, jump down and land on the bridge to pick up the cube and use the jump pad to get it back to the main area. Here’s where things get a little tricky. Make a jump cube and bridge cube and place them on the two panels to open the exit.

Make sure and reset their rewinds with the ‘R key’ once they’re in position. Place the jump cube at the edge where you used it to jump across before. Pick the bridge box up and, while holding it, jump across the gap. Then place the bridge cube to go back and get the bridge box. Repeat this again for the next gap.

In the end, place the bridge cube to get you all the way to the exit area.

Pick up the jump cube and carry it across using the bridge before placing it in front of the platform with the exit door on it.

Jump on up. Now, simply rewind time for both objects until they’re both back on the two panels.
