Corner Abyss

A casual match-3 puzzle game set in a fantasy world. A man in his thirties discovers a mysterious magic book and uses it for sinister purposes, challenging three women: Mia, an oni training to become a church knight; Elise, a demon and daughter of a demon lord; and Stella, a devout nun. The core gameplay involves swapping runes to create matches of three or more identical pieces in rows, which allows the player to attack opponents. Defeat each female character to progress through the game.
