Great story and the game is looking good. Do you plan to release your algorithm (as a code or paper)? I wonder how much does it take to check if a level is beatable.
I've long thought we'd see a web browser appear soon with a menu option to see how the user got to that tab's location. I'd use that at least once a week.
Isn't that just a back button? I supposed the issue is that opening a new tab doesn't duplicate the back button history into it, but I think there are extensions for that.
