Thanks Amos!
I'm definitely looking at a save game option - I can run this off the boardArray. Also some difficulty levels for one player play would be good. Possibly different map layouts, although based on the same sized grid. That would be useful once I start testing game play.
Probably the next settings panel I put in though will be developer tools. So that I can toggle on and off different elements and logs to check why bugs keep arising!
Adding developer tools sounds like a great idea!
