The game locks up like this at a few spots, we know what the issue is and are working on a fix for 5.5, but if you give it a few seconds it should resume normally.
No, not until around v.10-ish
I played the Manor like 4 years ago and haven't really checked in on that game since, not sure what you're implying by that - whether it's dev attitude or content plans as I think that game has changed a lot since I last touched it.
To answer your question, I update as often as I can. I had around 5 releases in my first year but the release window did grow as we went along and the game got bigger with more characters. V.05.5 will be smaller than v.05 so it will be out in less time.
There's around 4-5 hours of playtime I think, unless you don't read anything and burn through the dialogue.
I've been gone on break, bro! I'm back this week and am streaming a Brenda pinup tonight, the next doodle stream won't be until like the 13th I'm guessing.
