Hit refresh and INSTANTLY melted down. If you're going to push an update that messed with heat in a negative way, at LEAST make it so that the game starts paused so we can deal with it.
I already have the game sell all of your cells (For a full refund) when you update to a new version. But you're right, now that there's a 'paused' mode, that should be used as well.
I HATE that a slip of the finger ruins a perfect game on a 20x20. I would have greatly preferred it if we were allowed to mark things wrong, but then put in a check button that would check the puzzle and ding us time for everything we marked wrong. As it is, its stressful instead of a fun mental exercise.
I loved it, but two things would have made me love it more:
1) let you type in a number like others have said, and
2) Maybe give an option to grey out or fade completed nets, later levels just got so visually busy that it wasn't as much fun.
