That looks awesome °.°
I'd actually like to update the walkthrough with all scenes and their requirements, but due to a lack of time it just didn't happen yet. Even making a channel on discord for people to help with the walkthrough in a google docs file did only help temporary as everyone stopped working on it after a while. ^^" Maybe you're interested to help in this regard?
...or you could look into the walkthrough.
Q: What is the solution for Sandras treasure dungeon?
A: The code in the first area is 2-5-6-4. You get it by counting the things shown on stone plates hanging higher, not directly above the ground. A hint about the god is given saying „In his opinion only those who were above others had any worth.“, which is supposed to tell you which plates are correct and which to ignore.
