Loads of fun. Massive amounts of polish here too (and a level editor to boot!). Very nice :-)
I did feel like sometimes in the last level, the spaces between towers were wide enough that sometimes a baby wasn't near anything and I just had to wait and cross my fingers that they'd wander near a tower before the time limit, but small gripe. I found myself insisting that I finish the whole game even though one or two of the levels were tricky. Congrats!
