Fantastic visuals (the screenshots don't do them justice). Fantastic audio; the voice-sfx were quite and the jazz music made for a very nice vibe. Fantastic use of the theme. Fantastic gameplay.
I would have liked to been able to left click to mark innocent and right click to mark guilty (instead of the double clicking, which felt weird to me) but other than that the controls were good.
It took me something like 10 seconds to understand how the game actually worked. The little hints on the right were just enough for me to understand what to do; kudos.
Again, the music was great. I love the jazz feel with the casual-esque art style. The basic mechanic of deduction was really fun.
Genuinely fun game.
