Really well done puzzle game. I managed to complete all the levels with just a little annoyance here and there haha. But after all i enjoyed the feeling of success after beating harder puzzles. The mechanic of attracting the boxes is very polished but I found some bugs related to collisions:
this one happened when i tried to attract the upper box while standing on the other box
My button fell under the floor! Somebody help! oh, thank god i have restart
