Hi, I tried the new version but it doesn't help.
Here's what I mean by the box getting stuck
Sorry, I thought you meant it got stuck at the top of the beam when it floats up. I updated the game to make the platform where the beam is a little bit lower and to increase a little bit the power of the gun when the cube is near the player (But it is still too weak).
This should make it so it's easier to get it on the beam without getting stuck. Sadly I only got a Meta Quest 2 so I cannot test it on other VR headset.
I also added a video for the PC gameplay on this itch.io page and I added another video for the Meta Quest 2 here
