Line Color is a casual game where you have to move a colored cube through different courses while coloring in the line you're following. That said, you'll have to pay attention to the obstacles since if you run into any of them, the game will come to an end.
The controls in Line Color couldn't be simpler. Basically, you just have to touch te screen to keep your block on the path. When you come across an obstacle, you just have to let go of the screen and your geometric shape will stop advancing on the line.
As you move through each of the levels, the paths will gradually start to twist and turn even more. That's why you have to pay close attention to all the moving elements to make sure your cube doesn't run into anything. In the upper part of the screen, you'll see a status bar where you'll see your progress with the total amount of the path you've covered.
Line Color is one of those simple games that, while not offering a very surprising gameplay, manages to become more and more addictive as you go. The simplicity of its controls make it so that you just have to worry about beating your own high score in each and every level.
