Donkey King Kong Pro is a classic platformer in which players control Player as he attempts to rescue his girlfriend, from the Kong. The game consists of four levels, each with different obstacles and challenges.

The First Level: Player must climb a series of platforms, avoid barrels rolled by Kong, and reach the top to save girlfriend. The barrels and other obstacles move in different patterns, requiring precise timing and quick reflexes.

The Second Level: This introduces moving platforms and more barrels. Player needs to navigate through these moving platforms to progress, making the challenge even harder.

The Third Level: This level introduces "spring" that move across the screen, adding another layer of difficulty. Player must carefully avoid these spring while continuing his climb.

The Fourth Level: Player has to overcome multiple challenges before finally rescuing girlfriend.

Throughout the game, Player must avoid obstacles like falling barrels, fireballs, and gaps in the platforms while trying to reach the top of the screen. As the levels progress, the difficulty increases, requiring players to be more strategic and precise in their movements.
