This is such a cool puzzle! I'm still working my way through it but it's been fun figuring out the symbols. I'm stuck on what to do when I beat the smaller grid puzzles.
The game really needed some extra time to polish the whole experience. Rot13: Lbh xabj ubj, jura fbyivat bar bs gur svefg tevqf, gjb arj barf nccrne ba gur znc.

Yeah I got that far, but the small grid puzzles don't match the map size, and I'm pretty sure I've solved them correctly but nothing happens. At first I was worried it was the firefox bug that was mentioned, but I tried it in edge and it was the same. I'm sure I've just missed something and maybe I need to spend some more time thinking about it. Edit: Weirdly it worked fine in firefox on linux but not windows.
