I Will Purify You casts the player as James, an exorcist confronting Anomalies drawn from myths and folklore. These beautiful but lethal creatures are spreading chaos, and the mission is to purify them. Its premise gives the action a clear structure: travel across regions, survive their threats and face legendary female bosses inspired by different local myths.
Combat is side-scrolling and built around quick movement and attacks: dash, dodge and slash through supernatural enemies. Regions have distinct layouts, threats and attack patterns, while battles also yield materials and currency. Players use these rewards to unlock weapon recipes and Exorcism Powers, combining weapons to shape a build. Field items can alter builds or aid survival, and the listed design also includes stat upgrades, skill training and recruitable hunters with distinct abilities.
The game pairs waves of monsters with boss encounters, giving its action a mix of survival pressure and focused fights. Pixel-art animation and supernatural foes round out a design centered on building James’s combat options and taking on increasingly dangerous encounters.
