So far it has great potential

Just started and so far it seems to be fairly decent, Im guessing the puzzles will get more difficult as I continue. I love the interface and the clues are well worded.
In order to justify its price, I have two requests for improvement:
1. When I enter an O confirming a choice, I shouldnt have to fill in all of the other squares with Xs. I finished the first puzzle in 8 minutes but at least half of that time was because I had to manually fill in ALL of the other squares. Other similar apps have the Xs filling in for you.
2. The game actually will not allow you to make a mistake. This became obvious when I tried to remove an X that I had placed, you cant. If you try to enter Xs all the way across it will stop you when you try to put an X in the square that should have an O. I ignored this while playing because I wanted to go through the puzzle and figure it out but it MUST be corrected in order for it to be a true logic puzzle and a great app.

For $1.99 these two issues need to be addressed.
