I really like the art style used for this game. It really enhances the mystery of this unknown future and is overall very pleasing. I like the storyline and character interactions you have written. Admittedly like other comments, I originally thought the protagonist was female but it was honestly a very pleasant realisation when I found out he was a guy, especially with him wanting to be a nurse. Stella won me over with her charmful and upbeat personality. Not sure if it's intentional but to me, her almost oblivious nature to the troubles the MC is facing reflects how AI helpers like her would not be able to fully understand the emotions that humans would feel. To me small things like that enhanced the feeling of how despite the advancements in tech, its more focused on people's physical needs while leaving a disconnect with their emotional needs.
I think an improvement would be for players to be able to choose which memories are being deleted. Maybe when they select them it would provide the description and credits it is worth, then players could choose to extract it or not. Overall this was a really fun experience!
