Pretty cool, but...
...a change of scenery every now and then, beyond simply changing the location of the lily pad, would be nice. Also, it's a little odd that your "pondskater" can float straight over the bee hive.
As a practical tip, it's good to put an invisible shape behind your text buttons so that people don't have to click specifically on the letters to access a menu item.
Other than the above, this is a pretty solid, enjoyable little game.
