blockland portable was for a portable install of blockland aka on a usb drive which you would move between computers. since blockland went steam only it doesnt *really* work anymore as you have to be logged into steam on the computer you’re playing blockland on, which kinda defeats the purpose of using a usb drive to move your install around to any computer you want.
you can still run a portable install if you’re logged into steam on the computer you’re running blockland on
