It isn't necessary, but it provides another way to escape.
In an earlier version, there was a coin behind the barrel.
If you wish, the gate can be used instead of the barrel.
But not everything in the tent is necessary.

Your practice level gave me a crucial hint, but it wasn't the movement of the cubes...
Thanks a lot for this thrilling adventure.
