This game is currently under development, so the Patreon version only includes exploration up to Basement Level 7 (B7).
As updates progress, the current Patreon version (B7) will eventually be released to the public, and the next version will then become available on Patreon.
In this way, once the full game is complete, all content will eventually be made publicly available.
I'm really glad to hear the game suits your taste! But there's no need to make a payment — feel free to just wait for the public updates 😊
