Hello! I’m glad you like the game.
The Patreon is there for those who wish to support the project and the developer. While it does give access to a newer version of the game, there is no requirement to support if you are not able to (or if you do not wish to).
That said, the changelog for the current Patreon-only release (0.5.2) is now publicly-available on the Patreon. ♥
Thanks!
