    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.

My #2kPlus jam entry. The entire game in #JavaScript is under 2048 bytes when zipped!
u/andrea270872

wow... I have to look into this 2kplus competition
u/rodrigo.siqueira

The game is great! Sound effects could also be generated in pure JS.
u/KilledByAPixel

Thank you! I released a tiny JS sound effect generator that I use for all my stuff. But couldn't fit it in this. https://github.com/KilledByAPixel/ZzFX
