Curious what you used LMMS for, I couldn't hear any music. Love the aesthetic and that was really the only thing the game was missing. 

I greatly enjoyed this, with more polish it could really be something. A couple of things I noticed: you can have 5 faces but if the color or one feature is unique to the perp, it's very easy. You should think about countering this by checking first and adding a certain amount of matching features to the others depending on the level. Or you can just add a timer that rewards you for choosing faster, that would be easier and I think make it more fun. Really good and simplistic game!
