I was checking the Virtual Town page at LDW.com and look what i found

This means they have some pre-finished content, including a greenhouse?
(I feel like if i'm current successor of Jazzo, LOL )

That was in a very early alpha build and was dropped from the release. If you look it has placeholder text like "PLAYER COM STUFF THAT MIGHT GO HERE". It was used in the early previews of the game.

I imagine they found out it wouldn't work so dropped it. I suppose it's possible they might bring it back, but I doubt it.
