I generally like the idea a lot. It has a very "Papers please" like feel. But I think it lacks the stakes a bit. As I have all the time I need, I can just check the book all the time. No need to learn the costs or think much about the sins. Unfortunately that gets repetitive quite fast. I think for me it would have helped if there were less individual sins but more incentives to remember the costs to be more efficient.
But I like the atmosphere and sounds! It's a cool mix of ambient sounds and some funny sound effects! And the hand from above is so charming!
I think there is a lot of potential in this concept :)
