Dissappointing. Missing an essential feature to be a complete Sudoku Game.
Most Sudoku game on PC and Pocket PC have this feature. When I do a Sudoku in a newspaper, I write possibilities in each square to facilitate research. True, the DS screen is not high resolution and does not allow programmers to put a lot of small detail on the screen, but I think a Sudoku game missing this feature is not worth it.
Entering numbers is easy, graphics are not bad, and music can be turned off. But a good Sudoku game is based on it's gameplay, not it's presentation, and for the moment, it's lacking a very important feature. So I'll stay with the newspaper Sudoku for the moment.
