Version 0.4.0 of the game finally added support for a character having their sprites changed mid-scene during transformation scenes, on top of their avatar. You can get the game for free at itch.io or get the supporter version at Patreon.

Like what you see? Unholy Arts is a RPG/Dating Sim where all five co-protagonists have about as much agency as the player, with their actions, choices and preferences chosen by an AI that evolves with everything that happens in the game. You may want to seduce them or subdue them to win the competition and become the next High Priestess, but play your hand wrong and you will end up enthralled by them instead. Will the meek dryad turn into a lustful dominatrix? Will the bold and aggressive Tiger-girl find a way to accept love and intimacy in her heart? The game focuses on femaleXfemale relationships, with futanari content being optional.
