I would suggest a link to the proper version somewhere in the description

Ah, see sometimes a button or switch may control more than one puzzle element, I just checked and I don't think there are any duplicate signs that aren't connected. I'll double check but I may also have a tweak to declutter the signage

Well.. what do I say about this. I got the feeling that the jump in the first room does not work 100% of the time. So I needed several attemps. Then I came to the 2nd room and saw a lot, LOT of signs. The problem with this is that some signs are used twice... makes it confusing. I see what needs to be done but I don´t have time for this right now.

hmm, can't find the way to beat this. But i'll put it up to see if other people can.
