Wooow, its very good. This type of game which i can say it probably be in top 20. Good graphics, nice sound effect, and the most good - gamplay. You combined randomness of colors , but you win/lose not because of it. Without solid strategy you will definatly lose. But then you start thinking, this game becoming from simple platformer to sort of puzzle, there you need to have a strategy, there each worker should be. 10/10
