The folks at Scoreloop recently pushed out a new version, and I'm still figuring out some of the scenarios. I have a new version of the game at that same link that should correct the crashing you found on Game Over.
I actually tried the pause/hint method. Everyone that tried it said it was way too disruptive, and just turned it off right away. Each hint only shows once, and I might try removing some of the hints that are more obvious/less important to make it less distracting for first-time players. But either way I appreciate the input...
