i'm really sorry to anounce this but you can't play anymore a newer version of the game until you join his patreon, the test username and test password got removed by the dev after detecting multiples login's.
how his login system work ?
Patreon has an api allowing developpers to provide "login with patreon" button on their site.
So the way it works is way more simple, he download csv file from his patreon account.
It contains current patrons emails, that's the only thing he need. he generate an access code and send it to every patron in their mailboxes.
Then In the game launcher patreon type in his email, and the access code sent by email.
This way patreon have access to the game updates until he cancel his patreon pledge.
The game files are hosted on his web server, and they are protected by a password, can only be downloaded with a valid code. If there is some password leak, he can revoke access, regenerate them, and resend emails to every patron.
he makes things more difficulte for me, i decomplimed the exe file, i got into his website hidden page, tried to get a valid email and access code for you guys but they are protected by another password on his website, it makes me feel that he's protecting the next governmental futuristic weapon for the defense department.
i tried all what i can but i couldn't find a way, if you want more updates you must join his patreon.
