Thank you for your wonderful comment! As for the invalid URL parameter error, sometimes I've seen certain QR code readers erroneously shorten a long url, leading to a malformed link. Someone has brought up a similar error before, and the solution was to use a different QR code reader APP (https://github.com/evanbowman/skyland-gba/issues/7). Sharing in case this works for you, if not, I can look into the problem more!
