The atmosphere, emotions and engagement are all great. It feels that you invested a lot of time in the story and the characters. But, I was missing sharing some adventures with characters and involvement in their drama. I mean, we learn a lot through the notes and other lore materials, but as a player, you will prefer to live some of this through together with characters :) to learn who is who and why.
Dialogs are great and help to create the culmination. I love your art. The final scene is captivating. It wasn’t easy to read some notes due to the font. But everything else was smooth and neat.
Overall, the atmosphere is very mysterious. It will be great to have more puzzles hidden within. I tried different endings and would love to see more of this story if you plan to develop it later :) Thank you for the game!
