Any hope of a walk through mod [not outdated]?
Did you try it with the current version? It is only a minor version behind. Also I think the walkthrough is not really necessary. The game seams not to be mean or have really lose or win states. It is more of a story experience.
Tbh, I wouldn't go with the outdated mod for various reasons, a few of which I've outlined in the rant on the first post and won't go into again.
But more importantly, because of the way it's coded, it basically replaces a majority of the scripts to the version it was created on, in effect partially rolling the game back. That includes reintroducing all bugs, typo's and glitches, and maybe introducing a few where it doesn't roll something back for a change, and now it doesn't match with each other anymore because the new code is expecting stuff the old code isn't doing..
In addition, I didn't look it they ever went back and did a merge of the changes from the previous chapters with my fixes, changes and updates to the previous chapters (and there's a ton of those too), but my guess is not, because that'd require a 3-way merge a ton of code, and any developer will tell you that that's one of the most annoying task they'll ever get. So you're probably rolling the previous chapters back way more than just a minor or two.
All for something you didn't really need in the first place, but only thought you did.
