[WIP] Two Digits - A simple, yet very difficult, number game

Hi,
Working on a new game, Two Digits.

Two Digits is a simple, easy to understand number game, but is a game that can be very difficult and challenging.

In each level, you are presented with a set of 9 numbers, in the range 1-99. Each number can have three states, red, green or blue.
(States can be swapped by clicking/tapping)
The goal is to make the sum of the green numbers and sum of the red numbers equal.

It may seem simple, but not so simple once you start playing it!
The game will be launched on Android and iOS first, then on desktops as well.

Any comments about the game, the designm the concept, or the art style, are welcome!

 

Working on some tweaks.
