I’ve mentioned that Cultist Simulator has been through multiple prototypes. For your diachronic enthusiasms:
PROTOTYPE TWO. This was the ‘Alexis learning Unity’ prototype. No screenshots of this survive, thankfully.
PROTOTYPE THREE. This was Martin’s first pass at the desktop approach….
and the current, unfinished beta. There are changes yet to come, but the final version will probably look a lot like this.
