Very impressive soundtrack, such a great amount of tunes, I didn't feel the time passing by while listening to the album !
The summery beachy vibes are immaculate in the first half (reminded of the OSTs from Flower Sun & Rain or Paradise Killer) and the switch to a more eery electronic style worked very well. I felt that each track worked greatly on their own (could pretty easily envision them in situations of a visual novel where they are triggered at certain points of the story) and the whole thing also felt very cohesive when listening back to back throught the album.
I really liked the guitar playing in the various tracks, it brought a lot of energy and smoothness depending on the tracks so well done on that ! I'm not sure I can pinpoint a clear favourite from the selection since all the tracks were really great.
If I had to choose I'd pick Welcome to Port Corella (very catchy, energetic and works greatly as an opener), Your Search Begins (has a Layton vibe with the accordion and reminded me a bit of Windmill from Killer7) and I Wont Forget You (Reprise) (the live interpretation gives the track a lot of soul I feel).
Overall excellent submission and a very memorable one, congrats for your work !
