I would love to see implemented walkthroughs to unlock scenes, achievements, and outfits. Overall the game is very captivating and interesting. I hope to see a walk-through guide soon
There's a wiki for the Tales of Androgyny. It has achievements and outfits pages containing the info on getting them.
As for scenes guide, yes, something like branching graph with scenes would be cool to view in-game, because it gets really complicated with each new version.
The wiki is not up to date, last time updated in the 2 main pages for Walkthrough and Achievements was before October 2024 (6 months is not much but dev makes updates frequently).
