Anywhere sand and a crate is, the sand will be removed.
Ah. I think I understand what is supposed to happen. It’s a Sokoban-like puzzle, yes? Pushing a crate gets rid of the sand and shows grass?
For me, moving the crate does not remove sand, or have any effect. There are no errors in the console. The puzzle is unplayable for me :(
