At Stage 98 -- only two away from 100 -- the game crashes. Mobigloo tech support tries to help, but the problem remains. The company earns credit for making up for the unsolved bug. Nonetheless, 97 Stages make it worth playing. Also, there's no way to start over at Stage 1. Selecting "New Game" from the menu doesn't create a new game. It returns to the current game.
It makes no sense because there's a "Resume Game" option, but it's always grayed out when you enter the game. It only shows up when you're in the middle of the game and go back to the menu. Pushing "New Game" and "Resume Game" have the same result.
If you get stuck around Level 30-something or 50-something (can't recall exactly, but one of those), here's a hint: play with the switches.
It would be great to see more stages come out for the game (without bugs, of course) as there's no current substitute for Nintaii. Nothing out there grips, addicts, challenges, or takes little work in using the BlackBerry's trackball.
