Ok this is a very good game, this game gets pretty hard at each level, but it's pretty simple to play.
You run your mouse in the maze box, you do not want to touch the walls inside the maze. You left click the mouse button and hold it until you reach the red square at the end of the maze, then let go of the mouse button and the red box will light up. That means you have successfully completed the maze.
Click on the red box to move on to the next level and do the same thing again.
