Really cool idea! The ui is nice and simple if you have played other stacking games before. The mystery is not very difficult, but satisfying to solve.
On the constructive side, maybe it'd be good to color the different items in the formulas in the same color as the cards, so the difference between concepts like "evidence", "fact", and "alibi", is clearer. Also, some of the timers seem to take a long time (Bellamy + Forensic), which I did not really understand.
Overall it's great, though. Two thumbs up!!
