Black And White 25

A simple ABC based puzzle but with different rule and different fun.
The world is only divided into two colors: black and white.
All the same colors could be connected together to level up. Sounds easy? NO!
This game is easy to learn but it is hard to achieve high level and high score.
This game is a great challenge of your reaction and your strategy.
Your goal is to get 25. My lucky number. Hopefully also be yours.
