Can't update the post now, but I've actually got it down to 713 bytes, which I'm pretty happy with! I could remove features/colors/styles at this point, but I think I'll leave it there for now. If anyone's interested, I've tried to annotate a fair amount of the tricks I've used so far: https://github.com/lukebatchelor/url-snake/blob/main/golf/dev.html https://github.com/lukebatchelor/url-snake/blob/main/golf/de... let e=document.body,t="Space: start/reset. Arrows: Move<div><canvas id=a><style>#a{border:solid}{background:tan}</style>",r=40,n=400,o,d=[[4,3]],s=d[0],c="#000",p=(e="red",t=n,a=0,l=a)=>{C[f="fillStyle"]=e,C.fillRect(ar,lr,t,t)},h=(e,t=n/2,a=t,l="center")=>{C[f]=c,C.textAlign=l,C.fillText(e,t,a)};e.innerHTML=t,C=a.getContext`2d`,a.height=a.width=n,C.font="30px f",e.onkeyup=({which:e})=>{36<e&&e<41?H=e-38:32!=e||o||(o=1,d=[[4,3]],H=2,S=0)},setInterval(i=>{if(o){let[e,t]=d[0],a=e+H%2,l=t+(H-1)%2,n=([e,t])=>e==a&&t==l;if(d.pop(),a<0||9<a||l<0||9<l||d.some(n))return o=0,p(),h`:(`;d=[[a,l],...d],n(s)&&(d[++S]=d[S-1],s=[(D=new Date)%10,DS%10]),p`tan`,d.map(e=>p(c,r,...e)),p(i,r,...s),h(S,9,30,"left")}},n);
