It's a good game overall, not too long but not too short. The music was great and fit the tone very well. The voice acting was good as well, especially Edward's lines in the endings. The art was decent, but I felt like the photo backgrounds didn't really match with the anime style sprites and CGs.
I had no idea how to do the puzzle but somehow I managed to do it through random speculation, and I'm glad because I really liked the ending it unlocked. Both of the endings were pretty interesting and I was invested in this visual novel! It was a lot of fun, so thank you for making it!
Also I was wondering, when will the Extras menu be added?
