I bought the game on steam, and when I tried selecting a larger map size... it says I have a free demo version of the game? I can't seem to locate the key, so I'm a little confused on what the purchase I made was exactly.
Sorry @carthurlane I must have uploaded the wrong edition to Steam :-/
I will be uploading the corrected release presently and you should get the update automatically.
I may have accidentally bought this twice. I got a similar message after playing via the web browser version. I was playing, then tried to continue the same game. Apparently I can't finish that one? Or do I need to wait for a status change to my account? I used to know where to look for my status (free/paid) on various games/apps from/on this site, but either I forgot, it's not there anymore, or both.
