Loved the presentation of this one the sounds were great too.
Drawing the missing piece on graph paper is a fun mechanic.
The Stretch and skew elements didn't hit for me - its a fun concept to show that order matters but it found it quite fiddly to do (probably not the target audience)
I liked the UX of drawing shapes on the grid and would like to see more of that.
Overall I had a good time serving plenty customers - perhaps just a little too complex a game mechanic for me :D
