Unstable (schlenger)

Staple boxes until they get unstable. How to play? Click/Touch to add a box, hold it to move it and let the click go to place it. Wait until the countdown completes and do it again. There are some special boxes, beware their specs! General note: This is a little project originally planned for the Ludum Dare Jam 49, but Ive lost all the progress in between.
