An Undertale fan received an e-mail from their friend about his fangame, Underfell Yellow (actually it's a mod but the friend considers it a fangame). The player has been tasked with playtesting it and giving feedback to make it better.
Due to it being Undertale Yellow AU and a fictional mod, there will be some spoilers for Undertale Yellow itself. Be sure to play it before reading it.
