The aim of the game is to get through the labyrinth in a minimum of time.
To do that you have to use a strategy to calculate the best path through a labyrinth …
You will also need fast reflexes to avoid penalty collisions with the walls.
And, ultimate fine point, anticipating turns, will give tenths of seconds

You can also use a powerful, but dangerous, booster.
Powerful because when used, it doubles the speedups gained
Dangerous because if you collide with a wall under full boost you will lose all your speedups.

Each pastille eaten gives you a speedup point
Each eaten star gives you 10 speedup points
If you eat the cherry you will win 100 speedup points

The game automatically memorizes your best times as well as your best courses
You will be tempted to beat your ghost
