Really enjoyed this, it tells a good story. I got everything first try, though of course it took me a fair amount of time with all the evidence on the table to think through it.
At first, I was grouping the evidence by subject, and it was only when I had a pretty good idea of who all the characters were, that I started grouping them by who owned the items.
In a perfect world, there would be physical items instead of just pictures of them, and you wouldn't have to seal empty boxes for no reason before switching to the next one.
This type of 'story deduction' game is totally my jam. And it just works, it's tenuous at points, and the last box is mostly proven out by process of elimination, but it works.
