Level 1 to 6 are essentially just training levels, after that, it is full-on 3D Maze, Mazes within Mazes, up down left right full on 3D Maze !

And you even have to cross long narrow bridges that travels up and down !

The difficulty level grows slowly, so pace yourself nicely, don't play it all at once.

The game auto saves once you passed a level, you don't have to do anything about it.

This is not an easy game, once you have reached level 8, it will be very difficult to win without patience, like SERIOUS patience.

This game is not too easy that you finish it immediately, but not too difficult that you are unable to complete it.

This is not a perpetual never ending game, It's a game that you can finish/complete.

This game has an end to it and you can accomplish it with patience.
