What an incredible game. It has been some times since I had the opportunity to check out such a soulful little experience. I have "only" done two playthroughs, both on the "hero" route, but I will say I thoroughly appreciate how everything is written. Feels natural, adapted to the characters, and tasteful. It was a very enjoyable 7-8 hours, I thank you for them, and I'll definitely check out your other game.
To give a more constructive criticism, I would say a custom UI would be a big plus. I did not mind the photos as backgrounds, as I found all of them well chosen to represent the place, I never felt disturbed or annoyed by them, so I must commend the choices made. I enjoyed the headcannons used for some plot points, especially revolving around the pokecenter. Oh, I also enjoyed the interactive map, it helped keeping things coherent.
So, tl;dr, good game, keep it up !
