Giant Rush Online

Game description:

Start taking on entertaining challenges that can be both easy and time-consuming. On your way to the goal try to increase your character in size, by collecting little creatures of the same color as your hero. The bigger you are, the stronger you are. Avoid other colored men, otherwise, you’ll become smaller and lose your power. You have to get to the boss and finish him off with the strongest possible last hit, after which he will fly far away until he falls to the ground. It is at this point that the contest begins.
