    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.

[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).
