Reception[]

The soundtrack has been widely praised by games press and fans, with Eric Van Allen of GamingTrend saying, "The soundtrack to Undertale reinforces [the game's] earth-shattering moments, knowing just when to rise and fall, and the frequent use of melodies and themes subconsciously manipulates your heart throughout the whole experience. Each song is reminiscent of a time when melodies had to be simple yet discernible, and each piece finds a way to grow outside the realm of chiptunes without losing that simplicity."[3] Jim Sterling praised the soundtrack as "a damn fine collection of unforgettable tunes."[4]
