I've played through the first full level and started the second one. Barely started playing in other words. It's great fun though, and has some action/puzzle elements as you have to find hidden stuff to cram in your cart. I love the art style and the very odd tone of the game, and I love the Katamari like notion of collecting everything you can run over. It remains to be seen if it has Katamri's addiction level, but so far it looks good to me.
