Does this game have walkthrough?
It has, but it's outdated I'm afraid.
Also, if anybody here is a Patreon subscriber or member of Dystopian Project's private Discord channel, please ask them about the status of the remaining islands & when they'll be able to update the main story lol. And also, please raise concerns about the game's risks of being abandoned (that's what I'm getting based on recent replies).
Things don't look too great in the game honestly. I mean sure, we have some art in which we can fap to, and there's the Rivermont route, but that's more of an alternate route in the early part of the story, and they can't keep adding random quests while ignoring the main story. It's been 8 years. Plus, they still have two more islands to finish, which I assume where future major quests will take place.
