Oh tank you very much! Where do I find them? I killed the Werewolf and the arrogant witch, but in the gardens of Mausolea is no boss, only a sign that says "you've reached the end of content", and the high-tech-area is not opening after defating the witch.
Oh right, those new areas and bosses exist only in the up-to-date version released on my patreon.
This here free version is a very outdated one.
When I finish the development of the game (getting close to it!) then I'll release the full game here as well, but for now I'm doing sort of a closed-beta, releasing new updates exclusively on my patreon page.
