Play Gorilla Man, The (japan) Online

Gorilla Man, The was released for the Nintendo Entertainment System in Japan, though it never saw a release in other regions. It was published by Toei Animation, which might be surprising if you only know them for their cartoons. This game came out during the NES era when side scrolling action games were common, and it fits right into that category without trying to reinvent the wheel.

You control a character who can transform into a gorilla, switching between a human form and a powerful ape. Your main goal is to rescue a kidnapped princess by fighting through a series of stages filled with enemies and obstacles. The core mechanics involve platforming, punching and throwing projectiles at foes, and using your gorilla strength to break through certain walls. The game is known for its high difficulty, with relentless enemy placements and precise jumps required. Playing it feels like a constant, frantic scramble to survive each screen.
