"NOTHING YOU CAN DO"
I liked this! Very interesting worldbuilding. I loved putting pieces together in my mind about the story of the world (especially how new info brings new perspectives), I much less liked hunting down the last few runes - I was initially hooked upon discovering the Temple, but towards the end I didn't feel like I was finding any clues to hunt down their locations. This is where it stopped becoming engaging - something to think about.
But thank you for making this! I look forward to more worlds from you. :>
