Play Pokonyan! - Yume no Daibouken (Japan) Online

Pokonyan! Yume no Daibouken came out in 1999 for the Game Boy, developed by KID and published by Imagineer. It was part of that late-era wave of Japanese exclusives that never left the region, a colorful puzzle-platformer built for handhelds before the Advance changed everything.

You control a round, bouncy cat named Pokonyan, navigating through multi-screen stages filled with blocks, switches, and enemies. The goal is to reach the exit in each stage, which often involves pushing blocks onto switches to open paths or trigger stage transformations. A key mechanic is the screen flip; solving a puzzle might turn the entire stage upside down, altering your perspective and the puzzle's layout. You also collect items like bells and use a limited jump to avoid enemies or reach higher platforms. The pacing is methodical, focused on observation and experimentation rather than speed, and the difficulty comes from spatial reasoning more than reflexes. It feels like working through a playful, interactive storybook one page at a time.
