A couple of observations (non-game breaking bugs -- or at least missing QoL features).
There should be a function to export save games to a file. While this there is a workaround to transfer saves between PCs (by just copying from the game's save dir), there is none on Android, where it is impossible to access the saves (access to an app's files is protected on A9 and above. Renpy sync does not work so can't be relied on.
I really love the way the Violet character and interactions are written. TBH I would love to see more of her and less of Nel. It's really a shame that letting Violet take control is so cumbersome: unlike with Nel where you can run through a whole day at speed, the game falls out of autoskip after each battle, and her "self exploration" animations can't be skipped and run very slow. Why do I care? Because I want to increase her body proficiency to the max. Also, it would be nice if Violet knew how to use potions like Nel does, and adding the possibility to sleep when Violet brings you back home after a session without having to ask to be released would help too.
About body proficiency, it would be nice to have some indications in the wiki (or the Library!) on how it works and what effects it has...
