Despite rough edges, this interactive story is enjoyable and worth replaying. I love the emotional contrast between the ending outside the boy's house and the, err, other one. ;)
The music you chose is interesting from my perspective as composer. I composed Ambient Evening when I was about 13 years old and The Haunting when I was 21. Although the older tracks aren't as complex or well-mixed, the context of the game breathed life into them. I got a fresh perspective on my own music!
Did you write out the story and then choose the music at the end, or did you have tracks in mind at the beginning of the process? At what point did you decide to go with my music?
Beautiful Betrayal and Impromptu - Spring melded so organically with the two endings that I got chills. However, I think that the final note on Beautiful Betrayal should have rung out and then faded to silence, leaving only ambient noises such as wind or rain. Repeating the track causes those last notes to lose their eerie drama. The repeat of Impromptu - Spring also sounds awkward in the current context. Lastly in regard to music, the transition between tracks when entering a different area is slightly jarring. I slower cross-fade might help.
My complaint about level design is that there appears to be a few useless rooms that NPCs never even enter (correct me if I'm wrong). I wasted time my first playthrough exploring these areas despite the fact that they don't contribute to my understanding or appreciation for the story. This is a bit annoying when time in the game is limited.
Finally, there are small design details that I appreciate. I like how all the animal heads and decorations in Granny's House gives insight into what kind of man her son was. I especially appreciate how you incorporated the music and timed it to fit the emotional contour of the endings. There are many other things about the game I could comment on and ask questions about, but I'll stop before this turns into a rambling wall of text.
Thank you for the wonderful game and for using my music. I'd love to work with you in the future if you're ever interested. ;)
