This is a very interesting game! I've played through it and only got a 6.
I think the best part is the visuals and audio. Very neat interaction with picking cards and stuff. There was a problem where when I put the cards on the table I can directly click on the paper clips and other interactions on the card without zooming it out, not sure if this is intentional.
I feel like it's a very solid game that just need some improvements on some aspects.
First I don't really think notes and discard pile helps. For notes it refresh itself and you cannot click on it to direct to the card, plus you can only write down the underlined text, making it largely useless. And for discard pile, well, what's the point of discarding, when you can just put all the cards out, and then group them? If you discard something you'll just lose it.
Second I don't really get what's the meaning of making a draw pile and a hand, because to analyze everything you need all the cards out, especially when you get a card that contains a character you don't know. So at the start I just simply draw and put draw and put until all cards are out.
Third the case is soooo hard, it would definitely be a masterpiece if the player expects a very hard level, but to me the truth is so obscure. Reading the solution makes me feel that it's impossible to recreate such story.
Fourth is that you can return from the quiz to the investigation. I feel like the quiz provides a lot more information than the evidence LOL.
I think the most urgent fix is to make the discard pile, draw pile, and notes have a little more meaning (or maybe redo?) so that player will not just put all the cards out without caring anything. Also it would be nice to add a simple case where it's just a killer and a victim, no crazy things going on.
