I must need to work on my sleuthing skills. In my three attempts, I never managed to catch the double agent! Oh well, it was still fun :)
Your art choices fit together really well and the music set the mood nicely. I would just recommend altering character collisions a bit. Maybe they could collide with one another, or something, because sometimes a couple characters walk the same exact route (on top of each other), so it's hard to interact with the one I want.
Really great work here though! :D
