This is a difficult one to review as the game is very charming and well made.
My complaint with it is that it's way too short and far too easy. All in all it's more like watching a cartoon than playing a game.
But the game gets you smiling very often by using it's special type of humour, like when ... uhum ... i don't wanna spoil you here.
After all you get some replay value though, because there are three bonus games that are hidden in the game itself. During my first playthrough I only achieved the last one. And from that the only thing I can say you should definitely not await the bonus games to be any less hillarious than the main game.
Somehow this game achieves to take itself and the genre absolutely not serious in a way few games do so one could call it almost art. And the style of the graphics even underline this. It's made with love and you can feel it the whole game long ... well ... at least as long as it will last ...
I think you should get it on discount.
