It's quite easy to play just press q, w, e, r, t, y, u, I, o, p and so on. Just for starters follow the following pattern y, t, r, t, y, y, y, t, t, t, y, I, I, y, t, r, t, y, y, y, t, t, y, t, r, What's that song? WARNING: May be laggy so plz don't get angry. P.S You can't press one key multiple times in a go, u have to wait a bit in between.
All I can say is I thank a book called 'How to Code' by Max Wainewright for the idea. Remixes are VERY welcome just plz give me credit.
