It was surprisingly fun to build a tower from cardboxes. :-)
My first game was pure chaos, but in the second one I got a hang of it (although 6 meters is best I can do).
The movement feels little bit cluncy, but it might as well be by design - hard to tell. Visuals are simple (and sometimes little disturbing - yes weird "cardboard man" - I am talking about you!), but functional.
Good job!
