I ACTUALLY GOT IN https://rugbugredfern.itch.io/redmatch
PASSWORD: redmatch
I don't actually have a problem with anyone viewing the page, I just made it private so that it didn't show up in search results above Redmatch 2 since Redmatch 1 can't be played anymore.
i feel weird because i found the link, and somehow, I guessed the password.
pretty cool
