    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.

♛ QUEEN'S GAMBIT ♛ - Scroll down and up until the game starts (may take 7 times). Arrow keys move. Mouse aims. R restarts. God save the Queen! #Game

You will need to click on the canvas for WASD to start working, also fullscreen is recommended for this one!
u/KilledByAPixel

This is my full JS1k entry with some improvements, also playable on the JS1k website https://js1k.com/2019-x/demo/4211
u/metamero

wow this is ultra cool (and it really works, but you have to take a second afetar each scroll down and up - fortunately the game has a restart function)
u/KilledByAPixel

Once you've seen it you can just go to d/14024. In Chrome I can mouse wheel up and down super quick 7 times and it works.
u/KilledByAPixel

also WASD moves! It is wrong in the description, one of the enhancements over the js1k version.
u/13thptr

Very cool but it feels too much like cheating to me
u/KilledByAPixel

This is really just an experiment to prove out a system for using localStorage to string an arbitrary number of dweets together. I actually don't like that this is possible either which is why I went so extreme with it.
u/metamero

EVERYTHING on dwitter is about cheating!! (or one is going to say that these are the best programming practices) so stay cool and enjoy this awesome game
