Doing a bit of research, it seems that the devs have been rather silent up until last month. Publicly, the only info I've seen on an update is
"Still at it! We're happy with the direction it's going, but definitely taking longer than we'd hoped. Nowhere to go but thru!"
However, they are apparently sending out a semi-regular newsletter to the people on their mailing list. How do you sign up for said mailing list? It's hidden in the game files, of course!
(What?!?) Look for a file called "subscribe_to_mailing_list.txt" in the game folder. If, like me, you haven't installed the game yet, you can ask them to sign you up by sending them a message via
Twitter. They'll follow you back and send you a DM with a subscription link. If you don't have Twiiter, you can e-mail them at:
cardboardcomputer@gmail.com Why all the hoops to jump through just to add more spam to your e-mail inbox? I have no idea. Still, if you want to know how development on the last two acts is going, it seems like the only way, because their websites are no help whatsoever.
