Undertale

Years after a devastating war between humans and monsters, a child has fallen through a hole and into the monsters' underground world. Under the care of a kindly monster woman named Toriel, they learn the basics of the underground world, including that they may be attacked by other monsters who are less friendly. After the child leave's Toriel's care, it's up to them how they proceed through the underground, including whether they kill the monsters in their way or try to find peaceful resolutions to conflict.

Undertale is an Eastern RPG with some action aspects in its combat system. In the overworld, the player explores areas, solves puzzles, and talks to NPCs. When a battle is triggered, typically through random encounter, the game switches to the combat screen. A heart representing the child's soul appears in a small box, in which objects representing the monsters' attacks appear and must be dodged in real time. On the child's turn, they can attack monsters more directly through the fight command. A meter that determines the strength of the player's attack must be hit with good timing in order to deal more damage.
