I Want Never Gets

At the moment I am hoping to have a scoreboard so that players can compete with each other for high scores on each level; a level been the song as it will set the rate, height, amplitude everything but the size of the particles. Having other interactive elements and a progressive levelling system is the hard part now I think about deciding what to do. Scoreboard will have to be something to look into in terms of feasibility. I would also like if possible to incorporate the ability to add your own music and or play music located on line, again feasibility will be the issue, a) if it is even possible to do it and b) if I’ll have the technical knowledge to achieve it.
