Each of the 6 rectangular sprites play different keys, of an instrument. The instrument selection is random, and can be changed with the circular sprite (brown coloured). Press "a" for red key, "s" for orange, "d" for yellow, "f" for green, "g" for sky blue, "h" for dark blue. Press 'w" to randomly change the instrument (shown as a variable)
This is a remixed project, and I have made some alterations to include "randoms" and "variables". Feel free to change. Maybe, make the instrument selection more specific? or the key note sounds different?
