I made another tiny javascript game, this time a simplified clone of pong.

Play here: https://tilde.town/~troido/picopong.html

Sourcecode:
<body onload=b=p=d=2;setInterval(`s='';d^=2*(b%8<2|6<b%8)+16*(72<b|b==p);b+=d-9;for(i=80;i--;)s+=i%8?i^b?i^p?'.':'_':'o':'\\n';c.innerHTML=s`,200) onkeydown=p+=event.which%2?p<7:-(1<p)><pre id=c>

I still have to figure out what dimensions of the box to use for the most interesting gameplay.
