    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

[Falling Numbers 1.4] ADDITIONS: arcade style movements, proper score display (all though in the zero lane, the score still falls...), and a clearer objective (simply type what shows up on the screen that is falling).

Nice improvements! I think it would be fun with just 4 tracks? Maybe 1-4 or 2,3,8,9 for ergonomic reasons. Will get closer to dance dance revolution #DDR (which I'll admit I've played on a computer quite a bit) #interactive

Thanks. I made another update https://www.dwitter.net/d/8939.

pseudo trails / blur by additively drawing a semi-transparent rect over the canvas every frame. change the value of 'B' to increase / decrease 'trail' length
