Well they did say they were going to rework a bunch of stuff in their last dev log. Probably won't take much longer if they haven't already finished. I think we'll hear from them next month. It's not like they're not doing anything.
I am assuming you're asking when this game will be finished and to that I'll say, idfk. Maybe 3 or 4 years? Possibly more? Games take time and they're making two of them and they seem to care about their projects. It'll be done when it's done. There's not really much point in asking when it'll be done. Best let them do what they like doing until then. Whatever you do don't be like that Ewlamp1 guy.
