BRAZMON — Monstrinhos do Brasil 🐆🇧🇷

A Pokémon-style web game prototype where every monster is a piece of Brazilian culture and folklore. GBA-style pixel art (240×160, hand-drawn sprite grids), a 4-channel chiptune engine (2 pulse + triangle + noise, Web Audio), and zero dependencies — plain HTML/CSS/JS.

Play

Open index.html in a browser (or serve the folder with any static server):

python3 -m http.server 8000
# → http://localhost:8000

Controls: Arrow keys / WASD to walk · Z / Enter = A button · X / Esc = B button. The on-screen pad also works.

The demo

1. Choose a starter — SACI (Folclore), CAPIVARA (Bicho) or BRIGADEIRO (Comida)
2. Explore Vale Verde — overworld with houses, pond, festival arena, NPCs
3. Wild encounters — walk in the tall grass; weaken wild Brazmon and catch them with a BRAZBOLA
4. Trainer battles — four trainers (with Pokémon-style line-of-sight ambushes), ending with FESTEIRO GARANTIDO and his BOI-BUMBÁ at the festival arena
