The strings should have their own unique harmonic qualities that change with different movements. That is what I envision the game to be like as I play muted.
Just dropping the letters in with reduced alpha channel? At least incorporate them into the graphic. Game earns a "C" grade for flash proficiency & game design. 2.5/5
