I really loved this game..
except...
for one thing...
The physics when dropping things into the boxes a bad. They knock each other out of the box, won't go in the box, roll on the floor after being put into the box. That is not good. I had over 2 minutes left with the last item in my hand and I sort of 'stacked' it in the box with like 15 seconds left. It shouldn't take 90 seconds to drop the item in the box.
Also, when the order is filled, close the box so we know the order is filled. You have the beginnings of a cool game just needs a little work.
