As a fan of story-based games, this enthralled me. I played through twice and got the bad ending both times, but watching the plot and backstory slowly unravel before my eyes was captivating. I learned a lot about the world in the second playthrough that I hadn't expected based on my first playthrough. The limited colour palette and minimalist piano music really help sell the atmosphere.
In terms of criticism, I agree with what's already been said. Figuring out what's going on isn't too difficult - obviously I'm not going to give it away, though. But figuring out the exact path to take to get to the "truth" that I already actually know - or at least, I *think* I know - feels a bit like guesswork. I'm sure if I played through a couple more times, I could get a clearer picture of which leads are important and which aren't, and grasp my way towards the correct route.
But having to get a "game over" repeatedly in order to figure out the correct route... I'm sorry, but I have to say, it feels like bad game design. Especially if the correct route is *exactly* as long as the time until curfew (about 24 questions), and there's absolutely zero leeway. It's fine if you have to "game over" repeatedly in order to see all the different dialogues and get all the world-building information, but actually winning the game shouldn't be this hard to fathom.
I do like the idea of the curfew, though, especially how it's presented as part of the game world. As soon as I noticed the clock moving after every question, I knew there was going to be a time limit. Without it, you'd be able to beat the game by just methodically clicking every dialogue option, so it does press you to try and make the right choices instead of just "let's see what this one does". I just think it's too strict.
I also agree with those who said the notebook was too hard to open. On more than one occasion, I tried to open it and accidentally clicked a dialogue option instead. I don't see why you couldn't just make it pop up automatically after each dialogue ends. I also experienced the same restart issue as @alphish, just after completing the "name" dialogue - so I hope that one isn't compulsory!
I think I've sounded a bit negative here, so let me just reiterate: this is a fantastic entry with an engaging storyline, and definitely one of the most gripping Ludum Dare entries I've ever played. You should be proud of yourselves for developing such an excellent story. There just needs to be an easier or more intuitive way to get to the normal and good endings (or to know what you have to do to get them). At the very least, consider releasing a flowchart of how to get each ending after the jam is over?
...wow, I don't think I've written an LD review this long before. I think that in itself is a sign of how much I enjoyed this. Well done!
