A neat little game for what it's worth. Chimaki, the iconic mascot of the Guilty Gear series, controls like he's always on ice, which can definitely be annoying, but I got used to it soon enough. I beat all six main stages and did most of the Hard Mode stages afterward, but the last one really dialed up the difficulty (not in a fun way), so I decided to stop there. But yeah, Pro Jumper! is a pretty neat little forgotten oddity of a game. I'd say it's worth a shot if you're a platformer fan--just be ready for the slippery controls.
