Sorry but i have not understand what we need to do. We are able to push box and hang them but not able to combine them. It clearly miss a tutorial or at least an how-to play screen.
Thank you for playing. I was going for very simple exploration of mechanics. I think i gave player too much freedom, too little clues of what to do. Try dropping boxes at the canter of the screen.
that's what i try to do but nothing happen. Maybe not enough boxes.
