Play Chalvo 55 - Super Puzzle Action (Japan) Online

Chalvo 55: Super Puzzle Action came out in 1997 for the Game Boy, published by Natsume. It was one of those late-era releases that felt experimental, a puzzle-platformer that didn't try to fit any established mold. While many games at the time were chasing RPG depth or action intensity, this one carved out its own quiet, clever space.

You control Chalvo, a small robot that can transform into a ball, a spring, or a block. Each screen is a self-contained puzzle room where you must reach the exit, often by manipulating enemies or using your forms to navigate hazards. As a ball, you roll through narrow passages and over spikes; as a spring, you bounce off walls and enemies to gain height; as a block, you crush obstacles or block enemy movement. The game demands precision and forethought, with later stages becoming genuinely challenging as elements combine. It feels satisfying to finally clear a tricky room after experimenting with different approaches.
