Thanks for the compliments.
I hope you noticed all of the writing on the walls, and perhaps the cheat code box ;).
That was my save system. I kind of went retro with that one. Although, there's also coin saving. Don't worry about that, at least ;).
Also, by escape, do you mean the esc to main menu, or the quit by clicking on the close button?
The esc requires a confirm press, but honestly I didn't even really consider the close button.
