Could be better

While the interface is nice and relatively useful, it does tend to get in the way more often than not. Someone has apparently not bothered to put a whole lot of effort into this, considering the fact that it doesnt automatically clear pencil marks as soon as a number is provided unless you have auto marks on. Additionally, some of themes look frustrating, mostly due to the fact that they have different look on the same numbers, based on the square theyre put in. While that is a nice touch, it tends to get in the way. The difficulty level is jumpy at best, playing several games on the highest level presented me with some very easy puzzles, a few difficult ones and one that required guessing to solve.

Overall, too high a price for the quality offered and too much fluff instead of actually useful features.
