Nice graphics, but having to click to select the number to work on is too much, let us select with the keyboard. I also agree that it would be nice to be able to turn off the automatic recognition of whether a square is correct or not.
The rattle is way too hard; I couldn't seem to find the right speed or touch, so as soon as a baby wanted the rattle, the game was over. Also, no variation in difficulty was apparent.
