Tks for reporting that, i'll try to fix it soon.
About the puzzle, in the "basement" you can find this note:
spoiler:
Look at the symbol in the top left corner, it is a hint, also try to use it with the lines.
Hope this helps :))
I really dont understand this second puzzle. It seems like there is always something that messes with the pattern for instance. I add 1 and 1 and get 2 boom 121 add 1 and 2 get 3 then add 2 and 1 and get 3 again. 1331 okay 1 and 3 makes 4, 3 and 3 makes 6, 3 and 1 makes 4 boom 14641 now what if I do the same process I get 15101051 and I dont get what that means.
