During 2014 Jonathan Eng composed the soundtrack for interactive narrative experience The Sailor’s Dream, consisting of a mix of instrumental tracks and a seven-part musical story told in folk song-form. The soundtrack earned him award nominations at the Independent Games Festival and The BAFTAs. In 2015 a spinoff radio drama based on The Sailor's Dream was released, for which Eng also composed and recorded the music. The same year he started working on songs for Simogo's "Project Night Road" together with composer and producer Daniel Olsén. The game was later revealed to be the rhythm-action pop album video game Sayonara Wild Hearts. Sayonara Wild Hearts and its soundtrack was released in 2019.
