Down to 99, to make room for clouds at both ends

I'm very much a beginner here, and am still running out of characters :-) x.font="450px'";x.fillText('☁️ ☁️',90,1080)

Instead of 1080, you can write 2e3 which is short for 2000.
u/stiaje

Or 1e3, I guess :)

Also, because the dweet starts with with(x) you don't need to write x.fillText, just fillText, as long as you make sure to separate your statements with a comma instead of a semicolon!
