Thanks for playing.
1: That is correct. Zojoi played Infested and Spectacle and messaged me about us working on Beyond Shadowgate.
2: That is also correct. The design notes for Beyond Shadowgate had a blank area between the river and the desert, simply labeled "Ruins, maybe?!?", so I used the mansion found in Themeire, and reworked it to fit into Shadowgate lore. So the swamp and mansion were lifted directly from our defunct game.
3: We're working up post-production on Beyond Shadowgate (patches, feedback changes, additional options, possible console porting, etc.) and then we'll be beginning work on another project with Zojoi, that will be announced in a couple months :D
