Claude Fable 5.2 + Claude Opus 5.5
A Game Boy Color-style monster RPG in Spanish: collect 50 machine creatures, win six FUSIBLES and reach the Great Factory before the APAGÓN company.
MAKINAMON · Versión Pulso is a creature-collecting RPG in the style of the Game Boy Color classics, drawn at the handheld's 160×144 resolution and played in the browser. It's in Spanish.
A hundred years ago a bolt of lightning, the RAYO MADRE, struck the Great Factory MAKINA and came to live in its machines as the PULSO. Now the APAGÓN company wants to bottle it in the GRAN PILA and sell it by the kilowatt, turning the machines back into mere appliances. You play NIA, a rookie makinista, crossing the Valle de Ferralla with your Makinamon to win the six FUSIBLES of the power stations and reach the Great Factory first.
Made by gavilanbe with Claude ("Hecho con Claude Fable 5.2", says the README). The commit history credits Claude Fable 5.2 with the first prototype and the later polish (redrawn attacks, music with leitmotifs, sharper sprites), and Claude Opus 5.5 with most of the chapters and systems in between. The 50 creatures were modelled with distance functions and baked into pixel art by a script, and a test bot that switches Makinamon and heals checks the balance.
