Uhmmmmm... strange game. I got the end... but I really don't know why that person is the M****. : D
I think you must put the message in text, too. It's more easy for a non-english read english than ear it. About the sounds, I think that the messages are too much continuous. Maybe it could be better put more idle time, because it results very frustrating for the player.
Anyway, interesting concept. I liked the paint effect. :)
