Quite challenging, and the idea fit well to my mood (recently finished 2 detective games). I wish there was a few easier levels to start with so it won't be so disencouraging, yet I spent quite some time trying to crack the case and enjoyed it.
That's the problem if you don't have some testing audience available, you don't know what's easy or difficult anymore if as the developer you know how it works. Thanks for sticking with the game, I'll try to add an easier setting if I find time!
