This was such an impressive project. Excellent work with layering and 3D design. The sewers were especially impressive, along with your creative use of locks and keys. I really enjoyed the ending, although I didn't realize the point of the game until then. Even so, this was such a great project to stumble across!
Thank you! Yeah the main puzzle of noticing what sigil has all the right shapes is pretty obscure, especially the first time playing... but hey at least the bad ending is equally interesting/strange as the good one I think :)
Bitsy3d seems to have now some attractive new stuff like fullscreen view and custom resolution for images, so maybe I will try to make some kind of a successor for this in the nearish future.
