Out-of-the-blue bump caused to go look and see what the hell is going on with this one.
To my surprise, the project is actually alive - after a multiple year hiatus, Nonoplayer returned this August to announce it's being redone as a Unity game. Which really isn't a shock, since it was both way too ambitious for Flash and Adobe fucking murdered Flash. But they apparently couldn't get a Unity programmer until a few months ago.
It looks like there's a August 31 demo for the Unity version available on Patreon.
And now I'm surprised it's even still alive on Patreon, since last I'd looked at Patreon's rules "bestiality" was explicitly banned from the site.
