WHAT AM I DOING IN THIS GAME?
You role-play as a sociopathic cult leader, using emotional manipulation on NPCs to achieve your goals.
Through actions like 'compliment', 'flirt', 'insult', 'threaten', 'preach' and 'persuade' you influence the villagers' emotions (love, lust, trust, fear, envy, anger).
Gain their love and trust (or fear), persuade them to marry a Deep One, preach to raise their faith, and recruit them into your cult.
MAGIC: Allows you to develop creative ways to manipulate villagers even further, to the point of breaking the game. By studying documents, you can learn sigils that can be combined into spells or used individually to cast curses on households.
POWER: Your grimoire grants you the power to monitor all villagers' feelings, relationships, actions and motivations. You can foresee the outcomes of your interactions, allowing you to design schemes for manipulating the villagers to achieve your desired goals.
CUSTOMIZATION: Name yourself, your cat, grimoire, cult, village, spells and children. Try out various hairstyles, glasses, and hats. Construct, expand, and modify the village to your liking.
CATS: You can pet them. Cats bonded to you join you in your dreams, guiding your path.
THE SHADOW OVER INNSMOUTH: This game draws inspiration from H.P. Lovecraft's Cthulhu mythos. In the original tale, there are no cats in Innsmouth, making this one of the few deviations in the game. However, the narrative overall stays true to the spirit of the source material, free from any silly references or anachronisms.
