Cult of the Lamb.
Newly released, published by Devolver Digital.
It's basically BoI meets the cult management elements of Cultist Simulator.
It's got two parts: one the dungeon crawl, the other the Cult management part.
It doesn't do either section to the 9s (one cannot really compete with the variety of BoI on first release), and the Cult Management part by and large takes the form of building a few buildings, upgrading a tech tree, and a lot of daily busy work like farming, cleaning up poop, giving sermons, claiming Divine Inspiration from shrines that your cultists power up for you.....
That said, it's hella addictive. The *pacing* is all there. The busy work is busy work but it's about as quick as something like farming can be. The combat in the dungeon is snappy and responsive with a good amount of crunch and screen shake to keep it exciting. There's not the depth of transformative elements like BoI but it's a solid framework for more to be added. And the fact the game operates on a day/cycle means you're always measuring the seconds, moving through a dungeon as fast as possible to get back to your cult, maximizing efficiency while you're at your base so you can leave them it in a good place, so you can go on another dungeon run....good stuff.
There's lots of flavorful cult management features too, like dissidents you have to deal with, burial, brainwashing, cannibalism, rituals....all the stuff you want out of a game about a cult.
I basically haven't stopped playing it since I installed it. One downside is that the tech tree for the cultists buildings, cult attributes (called Commandments) and your own character's tech tree are completed long before you've even cleared the initial 4 bosses and their regions. So that's a little disappointing, but understandable in a game where you're constantly amassing upgrade resources on a daily basis, and the game doesn't FORCE you to seek out the dungeon every day. So if you want to just sit around your base and manage and build things, you're still progressing. But do too much of that and you'll find there's not much left to advance while you still have a lot of the dungeon gameplay to look forward to.
Anyways, I think the price is ok for what you're getting at $25. It's a rock solid base of a game that's enjoyable right out of the box, and they're talking free DLC updates which is promising for the future. Right now the game just needs MOAR, but what it has is already quite excellent. The style of the game is cute/evil with pretty nice animations and a quirky, enjoyable soundtrack.
