So very similar vein, uses many of the same mechanics and a lot of the same framework is Pathos. I think it's really well fleshed out even though I haven't managed to get very far. Amazing depth and mechanics but initially it felt like running into a brick wall for me. But the tutorials are very easy to read in the game and you can tweak a lot to become a god in different ways so you can test out and try to understand mechanics. I think it's great fun and kinda like a deeper, grander Shattered Pixel Dungeon!
