The game itself is ok, but the only option to save if you want to go back is to take a screenshot within the game, but if you exit and come back, it is gone. Also, the undo button doesn't work that great. It's not a straight Undo. If you're on notes, it'll only undo notes, if you're in numbers, it'll only undo numbers; Ex: if I enter a 2 and a 5, then enter 3 note numbers, and I hit info 5 times, it'll undo the last 5 note numbers, and ignore the main numbers - and vice versa.

I just downloaded this game and was working on my 3rd puzzle when I noticed an error as I was playing. I understand nothing is perfect, but I've played around 4 different games by 4 different companies and have never seen any errors like this. Sorry to say, but this is bad business especially with so many competitors out there...

This game is awesome. I only have two suggestions. It would be nice to have a automatic finish when you almost come to the end of the game & when its time to put in the last number in a particular column, it would be nice if that number is single out some way. That will top this game off perfectly. I'll be right here play your game. Thanks in advance.
