I'm not sure if you guys are open to constructive criticism or not, but I believe i saw somewhere else you were. If not, feel free to ignore this or ask me to delete it !!
I'd like to start by saying I really enjoy the custom trials in this game and I can see how much effort went into making completely original scenes. Its by far my favourite thing about the game and it made me actually interested since I don't know what could happen next.
One thing that did take me out of the game, though, was the characterization. Specifically Hinako's. I think making her someone to be suspicious of and causing conflict around her was a good idea, especially considering how she was one of the first suspicious characters in chapter 3, but I feel like a bit of subtlety in that regard could go a long way. For example, in the blue room, I feel like her entire argument felt a bit forced to stir up conflict with Ranmaru since we play as him. Its a minor thing, but I feel like pushing her to obviously and very loudly announce that she will kill the others so soon takes me out of the experience a bit.
Of course, it is only chapter 1-1 so maybe there are things planned that I don't know of yet. I never actually finished the game past the Keiji AI, since my game crashed and I didn't find myself interested enough to want to finish from my last save. But really, its only Hinako I had any issues with. Everyone else was done very well, I'd say. If I could make a suggestion for it, I think just focus on her values. She tends to focus on her survival and doesn't trust others. So (unless there was an alternative reason i didn't catch onto), in the blue room, I think it would be more realistic if she was fine with anyone except her taking on the role of challenger. If she just subtly allowed others to put themselves in danger by being passive and not acting to help them unless they prove themselves first. I think making her seem suspicious by being intentionally unhelpful and quiet might be a bit more accurate than making her outright attempt to murder the other characters.
Apologies if this comes off rude, I really do like this game and I want to see more of it. It was just that one thing that kind of bugged me, but please keep up the good work this is so good
