Too easy

Should be a little more challenging. A few updates a go one level was too hard for most people but they went to the other extreme with new updates.

Characters could be cheaper. More people would buy them and theyd bring in more money.

Some of the last levels (49 & 50 particularly) are annoying. Just too messy and not as fun to play.

Also, the review reminder is pesky. Asks too many times. Maybe offer a reward for a review.
