Thanks. Yes it's Amulet. There's a tool to make your own worlds using the same system here: http://www.vertexmeadow.xyz/
i've seen it, but not tested yet :)hey! i just realised that amulet is your engine! even cooler!
i've just played with vertexmeadow, is it the same codebase as southbank? it seems to be highly related :)
Yup, same codebase.
