Book of Eos is a fantasy RPG with a twist: You play as the monsters. Ozymandias is an imp living near the monster settlement of Detritiville, scavenging equipment and supplies just to survive, but when he comes across an ancient book, he sets out to get it translated and ends up discovering a legend that could change the world forever. 

Yeah, I know it uses mostly default assets, but I don't care. I made a freaking game and it's done and out and people can buy it!
