About Undertale
Undertale is an RPG in which you control a human who falls underground into the world of monsters. You must find a way out or remain trapped there.
Encounters
You can negotiate to get out of danger, so killing is unnecessary. Time your attacks to deal extra damage, then dodge enemy attacks in battles styled after top-down shooters.
Story and characters
The game has a character-rich story with humor, original art and an original soundtrack. You can become friends with all the bosses, and you can date a skeleton. There are at least five dogs; the game also jokes about whether there are six or seven, and about mistaking the third dog for another one.
