dump box (should be called donation box) is not a bad idea,
pw box is not a bad idea either, lots of people suggested it, clearly it has a popular demand.
key box is useless! just use pw boxes.
level box, useless! we barely use level doors!
color block~just get more plastics.
rainbow block: 2 blinding 4 me. *madman dies of epileptic attack.
block slices: RIP andy lu and his amazing glitch block designs, not needed, let andy do his thing
Autopads: spikes do there job pretty well, the auto pad sending you to the wild or to another pad is pretty useless.
As I said before, Color Blocks have no textures. The Auto Pad doesn't kill, you could link it to another pad or tell it to send you to the wild OR send you to the root. Level Boxes can be used as a newb proof recycle bin (but again it just popped into my head). Andy does glitches, not X axis wonders. Key Boxes could be used in a club or a clan.
I get bored of restating things.
