Enjoyed the puzzling, the box placement is a cool mechanic. I think the placement needed some polish though, as I had a hard time placing the boxes accurately to scale the wall to the third door. They always seemed to get placed in some orientation other than what I would expect. I wasn’t able to get to the third door because the boxes were not placing at the desired elevation, they seemed “locked” at a higher one than I wanted and I couldn’t maneuver myself into the door.
Overall, good effort!
