There is no demo. The game isn't even complete
Patrons just get the latest version earlier
I know my confusion was based on assumption. The assumption was I had to pay for version I got and then still got an inferior version.
Which wasn't the case. I understand most Patreon devs do the paywall thing. I am just going to wait till the game hits a 1.0 and see if I can by a complete version here.
