Mighty Hits is a light gun game with a wild west theme. The gameplay and stages are similar to Point Blank in theme and presentation. The game features cartoony cut scenes and menu screens throughout its design.
The objective of the game is for one or two players to compete in a series of mini-games, each lasting around 20-30 seconds. Players must complete objectives by shooting at targets, with rules displayed before each round. A results screen shows if the objectives were completed or failed after each round, and losing a life feather results in loss of feathers and game over.
Players can select from three courses: Easy (6 mini-games), Medium (9 mini-games), and Hard (15 mini-games). Completing hard mode unlocks a black tin can for Very Hard with 18 mini-games. The game is played in sets of three stages, where players must shoot three cards to select the stages. Bonus cards may be drawn after each set, allowing players to manipulate stage selection.
The game features a variety of mini-games, including shooting parts off dolls, playing a Three Shell game, shooting ice to free a penguin, and recreating melodies by shooting colored bells. Other targets include fish, bees, floating lanterns, toppling picture frames, and more.
