Imo, the blocks for the three flower sets, and the furniture from the sweets set, all look pretty flat textured. To a lesser extent so does the "test" stuff, but there it's justified.
Also, why are all the Zillium items Zillyhoo? I mean, you even have a spork and pistol, but they aren't the Battlespork of Zillywut and Flintlock of Zillyhau? The Zilly sword isn't the Cutlass of Zillywair and the blunderbuss isn't the Blunderbuss of Zillywigh? Why isn't the wand the Thistle of Zillywich? Since Dirk had the katana, shouldn't the armour belong to Zillywen? I HAVE SO MANY QUESTIONS!
