Play Hi Hi Puffy AmiYumi (J)(sUppLeX) Online

Hi Hi Puffy AmiYumi for the Game Boy Advance came out in 2005, developed by Altron and published by D3Publisher. It's a side-scrolling platformer based on the Cartoon Network series, fitting right in with the era's licensed games aimed at younger players. The visuals and music capture the show's upbeat, pop-punk style, though the controls can feel a bit stiff by today's standards.

You control either Ami or Yumi, each with her own guitar, as you move through levels hitting robotic enemies to clear a path. The main goal is to reach the end of each stage while collecting musical notes and avoiding hazards. Signature mechanics include using your guitar to attack foes and break objects, switching between the two characters for different abilities, and navigating occasional rhythm-based mini-games. The pacing is brisk, and the difficulty stays manageable for its target audience. It feels like a straightforward, cheerful adaptation that captures the energy of the source material.
