So do you want to listen to the game Soundtrack?
Just head out to the OST DLC page (http://store.steampowered.com/app/459110/) and add it to your account for free!
After that you can find the OST in the game folder at: Steam>steamapps>common>Mimpi Dreams> Mimpi_Dreams_OST
Hope you enjoy it! ːCuriousMimpiː
