Play Adventures of Rad Gravity Online
You play as a big-headed dude slashing through planets with a wonky lightsaber, then suddenly gravity flips and your spiky hair defies physics—classic NES jank in the best way.

Adventures of Rad Gravity came out on the Nintendo Entertainment System in 1990 from Interplay Entertainment. It was one of those late-era NES games that tried to push the hardware a bit further, with a larger world and more complex mechanics than many earlier platformers. You could tell they were aiming for something ambitious, even if the execution felt a little rough around the edges.
You control Rad Gravity, a hero with a large head and a laser sword, traveling across different planets to stop an alien threat. The main goal involves exploring screen by screen, collecting keycards to unlock doors, and defeating bosses. The signature mechanics include flipping gravity to walk on ceilings or walls, and using a limited-use jetpack for tricky platforming sections. The pacing is slow and deliberate, with some frustrating enemy placements and leaps of faith that ramp up the difficulty. It feels like a game that constantly keeps you guessing, both in its puzzles and its sometimes unpredictable physics.
