In UNDERTALE you play as a human child who falls underground into the world of monsters. Now you must find your way out... or stay trapped forever.

Welcome to UNDERTALE, an RPG game where you don't have to kill anyone. Each enemy can be "defeated" nonviolently. Dance with a slime. Pet a dog. Whisper your favorite secret to a knight.
Or, ignore this choice and rain destruction upon your foes.
But your journey will take determination. Each adversary has unique bullet patterns that you must dodge as well (don't worry, it's not that hard).
