Some instructions are in the project. Use the arrow keys to move. Touch a star to collect it. The light blue stars increase your speed by 25%, but they're not mandatory. You need to collect all the dark blue stars first- and then an X will appear in the center of the maze. Get to the X to finish the maze. Try to get to the X as quickly as possible.
Thanks to NobleLife for the original project. By adjusting the maze size, you can play in different ways. You can play smaller mazes, focusing on beating them as fast as possible, or bigger mazes, focusing on simply completing the stage.
