    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.

[Game: "Falling Numbers"] Prevent the falling numbers from reaching the bottom of the screen by pressing the number keys: 1-8, in the order that the numbers fall in of their lanes. Lanes are specified by the leftmost edge of the screen defined as one, and every other lane following is an incrementation of the previous .

Great job! A bit difficult to know which number to press. #game

Thank you, I improved the idea a bit with v1.4 (https://www.dwitter.net/d/8843).

a bit of a time leak since there's no enough chars to call x.beginPath(). If someone can figure out how to save enough to do, please do!

On this Mac 16em or scale(25,25) are the largest. But you can lower the width: d/7863
