Dennis brings Dennis the Menace's mischievous antics to the Super Nintendo console in 1993. The game follows the character's treatment of his nemesis, Mr. Wilson, as he navigates through various settings such as Sewers, the Park, and Mr. Wilson's house.
The gameplay is a standard platformer, with enemies that follow predictable attack patterns and can be avoided. However, some holes in the ground are deadly, while others lead to secret rooms. Players start with up to 9 lives and have the opportunity to collect extra lives throughout the game.
