the simulacrum is the playable room of yodidac. it opens in ancient rome — the forum, the workshops, the people who kept the city running — and the city is only the first layer. move with j/k, enter with ↵, and read the ledger it keeps of where you have been.
roma · aurum — the city, and the tutorial. postscaenium — what stands behind the set. trantor — how far a city can be made to reach. each layer keeps its own palette and its own rules; none of them leaves the simulacrum.
