    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.

Kudos! Interestingly, this looks very different in fullscreen, without the moiré patterns

Wow! The art for this game looks amazing. Only ever looked into the zombie crowd actions in the game.
