Very nice idea with the stress control. How the game mechanic is done it really gives you a feeling of controlling the stress. Cool take on "Guitar Hero" games. I think it is pretty hard (or I am completely untalented :D), so I would have prefered if it would start a bit easier and then gets more difficult. I also like your graphics and of course the audio. The songs you have chosen to cover, shows of your excellent taste of music :D!
