Reception
Adam Luhrs of RPGFan reviewed the soundtrack of Chapter 1 and described it as ranging "up and down the history of video game music" and also noted how the soundtrack "mash[es] disparate elements together." Luhrs also stated that there's "[a] thread of darkness and mystery that weaves through the soundtrack," citing that some of the tracks made him feel "uneasy." Luhrs said that the soundtrack "has a complete arc," and said that the included tracks "spark of creativity and clever thematic structure." The soundtrack for Chapter 1 was nominated for a G.A.N.G. / MAGFEST People's Choice Award in 2019.
