Fun and new: but it would be so much greater with a score system, to make it competitive and addictive.

Nice graphics and cute music, but:
* music loop restarts when you change level.
* It is very short.
* the game could be harder and more interresting if you could turn the pieces. As it stands, I feel it is too easy for a 4 years old kid (and younger kids pretty much don't use computers).
