This is really well written and you've certainly got that DE charm juxtaposed with the protagonist's horrible circumstance in your writing. I'd definitely be interested in a full release. One suggestion is to add some sort of skill mechanic that ties into the narrative. As he's an artist, maybe a few skills like Ideation, Meticulousness, Dexterity etc. that unlock unique dialogue/exposition. Although, that would take a lot of time.
Still, I'm looking forward to more!
Thanks so much! I really appreciate you taking the time to leave feedback, I've been thinking about adding voices in your head, that don't actually use skill checks but present themselves in a similar way to the Disco Elysium skills. So far I've been thinking of skills along the lines of Artist's Eye, Anxiety, Empathy, Ego. So when you have a thought that might fall into any of these categories you see a unique portrait attached to it just like Disco. That way I don't venture into RPG territory which would definitely be too ambitious for me.
Btw I took some time to play and send some feedback on the game you shared, hope it helps! I can see you took a lot of inspiration from Disco as well :)
