You simply need to enter each one once. After you've entered all 5, the gate will be open in the secret room in the cyan area. You do have to climb a very tricky wall to get to it.
As a warning, the reward for getting past this is the hardest area in the game. And there isn't a reward for completing that challenge other than having the full map completed. Just letting you know ahead of time in case you choose to take on the challenge.
Dude, I found and... and... I never understood why Tom Cruise's movies got the title Mission Impossible... Now, seeing this wall to climb, I understand what Mission Impossible really is... Dude, dude... Your game is really great. Really, really... And I loved the difficulty of each part. Well, well, now i think that i have a daily challenge to try.. Thanks for the game and hints and Congrats for the skeletons.. :)
My next message, If I can, it will be a print of the complete map :D
P. S. "hardest area in the game" ? ooh yes, I'm super interested now...
