The game idea at first was to develop something related to the mathematic factorial operator, thus having an incremental or decremental object adjacent to each other.
Thus the 9X9 matrix with the factorial 5, that is the sequence from 1 to 5 was the best to introduce a challenging brain teasing puzzle for the beginner puzzle gamers, and a for the advanced puzzlers the number of moves and the timing was itnroduced so that they have a chance to score higher, if they can ;)
As for the graphics since the game design started after the release of the Android L (dubbed later on Lollipop), the game followed the Android L design guidlines and color themes. As usual a perfect engine for this small puzzle game was andengine: light, fast and an epic 2.8 mbytes APK size.
