Regarding the reflection of values in one's game, I agree with you completely on how important it is to stay morally consistent - in fact, I'd argue it extends way beyond game development and into other aspects of life, including relationships, daily jobs, posting on social media etc etc. Keeping morally consistent is definitely not trivial, though one thing is working a boring job because you need to pay the bills, another is working a job which may be interesting but involves exploiting people in the way you described. And sometimes it's just not clear enough what your values are, it might just be not possible to self-reflect at all...
As for your concerns on turning mental wellbeing into a selling point, I believe some non-game related analogies can be made as well. Smartphones are a very clear, though perhaps too broad an example seeing how much they changed people's lives - they were meant to make people's lives easier, just like the personal computers back in their early times, however they also now both serve as the hosts for all the media, both useful and detrimental, and the way (most) phone/computer companies handle device distribution is purely oriented on sales, which as we've already concluded involves removing all self-restraint. Thus with time the users attained less and less control over what they buy, even changing a battery has become an impossible task for a layperson, and all the preinstalled apps competing for your ever shortening attention span...
This is definitely a topic for another wall of text, haha, I guess it's just how it has to be, though for me personally it can be difficult to keep track of what I'm wallposting about since there's always so much on mind. Perhaps we could connect on discord or somesuch sometime so it's easier to talk in short bursts? Here's mine just in case: Aru#5023
In all honesty I'm really excited for Aether Fly's possible future! It was one of my favorite games in the jam and made me feel in a way no other game I played did. And yes, a future collab sounds exciting as well, I feel that our game design visions are similar yet different enough to complement each other, so when the time comes I'd definitely like to try and work on something together with you :)
