About Undertale Yellow
Undertale Yellow is a fan-made prequel to Undertale, where you control Clover, the seventh human to fall into the Underground. Just like in the original game, it will be possible to finish it without killing anyone, or eradicating everyone. Grab your cowboy hat and your gun, and help them on their journey, meeting with friends new and old.

Undertale Yellow is directed by Master Sword, with a demo available on the IndieDB page.
