    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 .

u/joeytwiddle

Great job! A bit difficult to know which number to press. #game
u/MrM@_S

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

Managed to create a flat sea. Had to trade off the nice distance fog effect.

Replace Y<L?Y:L with Y and you'll understand how the flat sea effect was achieved. Nice one. ;)

This one has water - not flat unfortunately. Had to trade off the pseudo-shading to fit the colour change int
