The concept hasn't changed: the tiny Prince must impress his disparaging dad, the King Of All Cosmos, by rolling items of increasing size and surrealism into a worthy ball of junk. Start little, grow large: it's the Katamari way.
Skip the touchscreen controls - the thumbsticks feel sublime, while the shoulder buttons make it easier to switch direction and to jump. It matters: most stages (many recycled) are punishingly strict, requiring you to grow your Katamari to a certain size within a time limit, or to pick up or avoid certain items.
While you can download new stages and items, you can instead unlock them by collecting sweets, baby faces and Spirit Fans - it's a little complicated, but the option is there.
We'd have liked a few more open-ended stages and less pop-up, but Touch My Katamari is still a fun and funny launch title for Vita - eccentric and bursting with charm.
