The Mouse Maze description

Your character is a little mouse that needs to eat a specific amount of cheese in each level. You need to collect them all before time runs out or be captured by the cats that walk through the maze.

In addition to the cheeses, you may come across two other items. One of them (green vial) replenishes your health if it has received any damage. The other item (yellow colored vial) increases the player's running speed.
