press any key to stop the moving block where it is. Try to stack the tower as high as you can while staying in the turquoise goal area. Getting past the check Points will change your tower , try to get to the green tower on all the levels! As you build more height you will also earn stars! The star meter at the bottom will tell you how far along you are in getting your next star. But be careful! as you go on the levels get trickier, with faster moving blocks, smaller goals, and higher up check points!
