    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.

try this version in a new dweet (acceleration control with up arrow, but I couldn't golf it enough): !t&&(d=[a=v=0],X=Y=99,onkeydown=e=>d[e.keyCode-37]=1,onkeyup=e=>d[e.keyCode-37]=0),x[f='fillRect'](X+=v*C(a+=(d[2]|-d[0])*.1),Y+=v*S(a),s=32,s,x[f](X+C(a)*s+8,Y+S(a)*s+8,9,9,v+=d[1]&v<6?2:v>0?-.1:0))

`t?onkeydown=e=>d[e.keyCode-37]=1:(d=[a=v=X=Y=0]),onkeyup=e=>d[e.keyCode-37]=0,x[f='fillRect'](X+=v*C(a+=(d[2]|-d[0])*.1),Y+=v*S(a),s=32,s),x[f](X+C(a)*s+8,Y+S(a)*s+8,9,9),v+=d[1]&v<6?2:v>0&&-.1
