First off NO IAP!! In addition, this is the first puzzle game I've ever played as a subtraction game and it's amazing! surprisingly simple and difficult at the same time. As is it's a wonderful way to burn a few minutes and a nice exercise of mental math but what would make it better is more power ups, achievements, and one more gameplay mode, as is it has a race mode where you have a timer and you try to get the highest score possible, and then there is a normal mode where pieces fall from the top and you try to keep the screen from filling up. This game makes math fun like cheese makes broccoli good, the game is well worth the 2.99 price tag due to gameplay being so unique. Nozoku rush is off to a wonderful start the only thing it can do is get better and with future updates I hope that is exactly what the developers do.
