    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.

Abstract smoke! Nice! Could look nice if it left a trail?
u/joeytwiddle

Tried shadowBlur but very heavy. Trails look better anyway: x.fillStyle='#fff3',t?x.fillRect(0,0,999,800):c.width=999;x.beginPath();w=540,t?m=[w+S(t)*340,w]:p=[];p.push([[...m],5]),p.map((z,i)=>{k=z[0],k[0]+=S(i+t),k[1]-=z[1]+S(i*8),x.lineTo(...k),x.stroke()})

Oooo, I like that, great idea! I'll have to try incorporating that into a remix. Thanks joeytwiddle!

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