Probably a very easy maze game. The ball will keep going to move. Use the arrow keys to change direction. Get to the checkered flag to win! When you finish the maze and touch the checkered flag, there is another maze! Reach the checkered flag to only find out there is yet another maze! With a shortcut... PORTALS: They look like a coloured square with a grey outline. Touch the portal with a darker outline to get teleported to the other portal.
