The Heretic's Seal uses generative AI for some pre-rendered art assets, including character portraits, enemy and NPC illustrations, world map and biome backgrounds, and select promotional video clips. As a one-person studio, AI tooling lets a single developer ship dungeon-crawler-scale art volume.
All gameplay systems, game design, narrative writing, code, level design, and runtime visuals are created by the developer. No AI runs during gameplay — every system, decision, and reaction in-game is hand-crafted code.
