I read the OP thinking, this game seems as crazy as Katamari...and then came across your comment. The original Katamari games were so mindblowingly great that I'd buy anything Keita designed

They were AWESOME.

However his next big thing 'Noby Noby Boy' was just too weird and kinda pointless for me. He's certainly one to watch, and I'd probably shell out for his games regardless, but he's not 100% guaranteed to make something great each time.
