Play Jelly Boy 2 (Japan) (Proto) Online

Jelly Boy 2 is a prototype platformer for the Super Nintendo Entertainment System, developed by Probe Entertainment and never officially released. It exists as an unfinished build from the mid-90s, a time when the SNES library was rich with experimental and visually bold titles. The game stands out for its surreal, high-contrast aesthetic and unconventional physics, offering a glimpse into a project that never reached store shelves.

You control a stretchy, gelatinous character who navigates a series of abstract, screen-based levels. The main goal is to reach the exit in each stage, which involves bouncing, stretching, and slingshotting yourself across gaps and around obstacles. Two key mechanics define the action: your character can latch onto certain surfaces and stretch like a rubber band to launch forward, and you must also avoid melting in water or getting crushed by moving parts. The pacing is erratic, and the difficulty feels unpolished due to its prototype nature, but the sheer weirdness of moving through these vibrating, neon landscapes gives it a unique, almost dreamlike quality. It feels like manipulating a living inkblot through an animated sketchbook.
