After reading the comments I was quite intruiged and ddetermined to solve it hehe
It was quite a nice experience. I was careful of finishing the interogation, which seemed to be the right decision as you seem forced to accuse if you finish talking to all of them.
Lucky for me I had gone through all, maybe not, of the permutations of the dialogue when I finally accidentally pressed Finish Questioning on the last character.
The only small things I found that seemed to have gotten past the polishing was:
1. Diamond ring in notebook seems to have the wrong image (Champagne glass)
2. The thing I mentioned above
All in all, a really nice game with REALLY nice art and fitting sound. Loved the vibe!
Well done!
