Solutions are good when you get stuck and would otherwise quit playing. The linked pentomino solver is perfect for computationally solving the puzzle locks, and you still have to put in a bit of effort.
Your image of the solution for the element locks is a bit „in your face“ and could be tempting to skip this part of the game. I would appreciate if you could please remove the image from your post (after all it‘s the first comment below the download button). If there are more requests for help with this specific riddle, we can give hints specifically tailored to get a nudge in the right direction without giving everything away.
I‘m a bit surprised you didn‘t include a map of some sorts ;) If you made one, feel free to send us a picture of it via mail (address on the game page). We‘ve received a few already and it‘s always cool to see each individual approach to the maze :)
