Nice!
You know, you really got it right by making the game 20 levels... it's just like a skirt... short enough to keep me interested but long enough to cover everything. The diary was a cool feature that I unfortunately discovered on day 19 (thanks to a reviewer). I really liked the atmosphere of the game, from the fog effects to the markings on the to-do list (an old recipe... awesome!). I don't know how long the #1 position is going to last, but you definitely deserve it!
Oh, I don't know if this is just me or not, but were the women toward the bottom of the screen supposed to resemble Jill from Resident Evil?
