I need to play with the SDBs more; they're not lined up right. I'd like a couple more probably, and also the melty coffee table. But I'm out of credits, so I'll do that in July before moving on to my kitchen. Also known as the jelly display room.
There aren't any PC Katamari games, but there's a ripo- uh, I mean, an homage to it available on Steam called The Wonderful End of the World. Of course, that also means it doesn't quite directly benefit from Keita Takahashi's unique weirdness, either.
The cracked floor and the person-shaped hole are his too, so the crack went off to the left :-D
