The Shapes have suddenly become mixed up! Your goal is to stop them before the timer runs out so they can be put back in order again!
There are 2 ways to change the pointer type...
1. Simply click the left mouse button until you get to the desired shape
2. Use the numbers 1 - 5 to accurately select the shape you would like to use (Recommended for later levels).
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
