Thanks for the feedback. I didn't know about the [esc] button in the audio settings so I'll check that out and I'll definitely change it so that the lock/unlock doesn't get reset every time it was just something I didn't have the time to get to yet. The escape button doesn't work in the start screen because its assigned to the back button I was on the fence about that one so I'll probably change it to be the settings button there as well. A Lot of the feedback seems to still be around the difficulty or how annoying it is to actually draw out the solution so I'll be spending most of my time on creating more tools to hopefully make it easier.
