I love the atmosphere you've created. I actually enjoyed reading through the manual. At first begrudgingly, because I thought "ah man, tutorial.". But seeing the bizarre rules made me do a double take. I needed to explore this world. Lucky for me, the characters gave me a glimpse of the happenings in wider society. This is the truest depiction of of a soul reaping bureaucrat I've ever seen.
I got fired the first day. But that says more about me than you. I was busy admiring the details. I also didn't know it was timed until I heard the warning ticks. The UI gets in it's own way a bit. You've transcended the need of UI thanks to the artistic detail and well established rules. The immersion happened surprisingly fast. The manual was my friend.
This is in fact, a top notch grim simulator.
Honestly, It'd be cool to hear about the brainstorming that lead to the different religions and this concept as a whole. You guys are weirdos. The kind of weirdos who build worlds. Great job.
