Colorize

You will be our "hero", a little colored square.
You will need to click on the screen when it is the same color as the floor, thus making a hit and increasing your score.

When you reach the end of the screen, if you haven't clicked on the screen yet, it's the end of our "hero's" journey. But don't worry, you can try again.
If you clicked correctly, when you reach the end of the screen, the "hero" will change color, as will the floor, and the game continues.
