Really cool game !
Though I had some issues with it, probably because I never played Papers, Please! myself.
First off, it took me a while to understand how to turn pages. You should probably add a short message to explain it somewhere as playing without being able to open the books is impossible.
After figuring that out, I had a good experience, I was doing perfects or just 1 mistake, most often I forgot to check the weight. But it was going smoothly.
Until day 6, with the return addresses. I retried the game like 6 times, I was doing everything right and every single time on day 6 I got the return addresses wrong.
I first assumed the return address was the last line, because by that point I had tried flipping the letter the same way I turned pages on note stacks or books, but it did nothing despite trying lots of times, so I was convinced you couldn't.
I thought it might be wrong initials ? but no, those were correct on many letters.
Maybe it's the format of the whole line ? nope, they are all [2 letters] [2 digits] [1 letter + 1 digit] and still some wrong some right
One of them had the recipient be "Mx EDWARDS" and it turned out the return address was wrong, so I thought maybe that name isn't the recipient but the sender, and Mx is incorrect ? wrong too, as another letter had "Dr TAYLOR" or "Rev SMITH" but it said return address was bad.
I seriously was confused. I thought day 6 was not supposed to be beatable and that it was some sort of cheap way to make a forced ending.
Turns out you can flip them by clicking in the bottom right corner. Up until that point I assumed the entire left and right sides were the triggers, and had I not recorded to try and check what was wrong in post, reviewed it and noticed I hadn't tried spam clicking everywhere on the letter, I would have left a significantly lower note.
It also really doesn't help that clicking in that corner while the letter isn't selected doesn't flip it, so when you're on the town almanac you have to click the letter twice to flip it for example.
Thankfully though I gave it another try and confirmed it was in fact on the backside, where I was expecting it to be.
Anyway, TLDR is it's not lacking much in terms of tutorial, but the turning page and flipping letter interaction really weren't obvious to me and nearly made me very frustrated with this otherwise really good game.
My only other critique is much more tame : I wish the font had a bit more pixels, as it was a bit hard to read, I got used to it after trying again and again but still.
All that to say that it's crazy how a simple small thing can make such a huge difference.
I think a couple solutions to solve this would be : - Have a tutorial step ensuring the players knows how to open the book, you have the call button blink, you could have a rectangle blinking on the handbook to show where to click. - Change the cursor when hovering over an area where flipping is possible - Could also have a different interaction to flip, maybe double click or MMB or a keyboard key that would work no matter where it's done (though that could still lead to problems if you try normal clicking on the side and don't try this method)
I did beat day 6 in the end, at least it was the last day so had I not found the flipping interaction I at least wouldn't have missed any content, apart from seeing "promoted" at the end I guess haha.
Well anyway, great game still, I had fun and liked it enough to give it many more tries than the average jam game !
