Source of Madness is a side-scrolling dark action roguelite video game developed by Carry Castle and published by Thunderful Games.


Source of Madness takes place in an alternative reality where the world did not go into the age of enlightenment, where magic and the monsters of Lovecraft exist or rather allow you to exist. The world is steered and controlled by cosmic entities where the human race hangs on in foolish attempts to survive for yet another sunrise. You play as newly initiated acolytes at the tower of knowledge, where people of Loam have taken shelter from the disturbing hordes of monsters currently infesting the Loam Lands.

Your voyage will not only be one of the depths in terra nor only the depths of treacherous forests but to the grand non-euclidean citadel R’Lyeh, to the moon, and the celestial bodies on the rims of the universe!

These worlds warp and distort with the current unstable space time leaving things each day different and inhabited by deformed and grotesque beings of celestial origins. You are only protected from the warp by the powers of the Tower of Knowledge, yet now you have to voyage out, to find the twin tower, the Tower of Madness.
