Can you tell me which one exactly so I can fix it? :D There is no such things as dev version though, I only have early access and normal versions. Make sure you don't download those fake "new version here" stuff. Those fake versions will run Javascript code on your PC which steals all your browser passwords/discord tokens/steam login/etc if you simply start the .exe file, so please be careful and only download from trusted sources.
I don't know how many I have planned and since I'm working on this in my spare time, I can't give exact release dates. Sometimes I'm too exhausted after my normal work and other times I just have to do normal things which prevent me from working. It'll probably be less than 8 month since last release, which was in April, so expect it roughly in the last quarter of this year.
You can download the walkthrough mod or PDF directly from itch and follow the "ideal" path. You probably have just missed that scene then.
