For some reason when I tried to drag the crates int the first level I couldn't move?
I initially intended to make the boxes draggable, but the physics was buggy so I decided to make them unmovable. Unfortunately, I forgot to change that in the dragging script and the character will still attach to them.
But wasn't that part of the core gameplay? Maybe I misunderstood that. Either way you should probably update the description then.
In the first level you can drag only the ladder, the boxes cannot be moved.
oooh the *ladder*
