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", also noting 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".^[6] The soundtrack for Chapter 1 was nominated for a G.A.N.G. / MAGFest People's Choice Award in 2019.^[7]
