Well..
Sometimes it is just fun to call shenanigans. I, however am not. I very much enjoyed it. One bug I did notice is that sometimes when you restart a level one or more of the blocks will be gone. This can make it so that the level becomes unwinnable, in particular I noticed this in level 20 with 3 blocks rather than 4 in the center. It seems to get better if you quit to the menu and redo the level. Other than that great game. Keep up the good work.
