Perfect and uniform like the boxes you push in this video game...
For the kind of game it is I can't think of many complaints aside from a few aesthetical nitpicks like the lack of movement animations for the boxes and player but bah who cares - good stuff! I loved the change color option, though the option probably would have been better off if it was usuable outside of the only the title. Maybe after every level it could have changed, or it could have had its own dedicated button for funsies.
Nice variety of levels too; a few of them had me decently stumped! And it was refreshing to sometimes have an easy one after dealing with a few tough ones in a row. I liked it a lot.
