Big fan of this teaching game. I rate this game as my best ever experience (Braid, Seven Kingdoms are two and three rank respectively now).
Clicking on ‘Play Circle Walking’ this link: http://us3.campaign-archive2.com/?u=c86c5e56e46659873417a8f1c&id=03a7bbfd67, I can access the first level of Kelvintaph Glacier sans unlocking the world (yet). Is this intentional? To tease players, etc? I haven’t tried playing it and checking if I can submit solution and earn the diamonds to my account (or if finishing it can repeatedly pump diamonds into my account ).
Hope this is not an adventurer level that I accidentally came across.
Big fan of the game
