yes python3.9 sets the requirement
9.16.3 worked fine
Okay, here's a download of 9.17 which is the last version before I upgraded to Python 3.9:

Like I said, I will not support this version with any backported fixes or improvements or anything. But the pace of Playscii's development is pretty slow these days anyway, so you're not missing out on anything really.
I am still curious as to which version of Windows you're running, just so I know which versions supports what.
