I would kinda like to see this approach (Kaboom) combined with Simon Tatham's version. Basically, add the guarantee that you can solve each one without guessing. Or, add instant death when you open a square that wasn't guaranteed safe to Simon Tatham's version. I think I would like that significantly better: I like the guarantee that each one can be solved, but I want to be punished when I incorrectly open a square that wasn't safe.
