About ECO Guardian
ECO Guardian is a 2.5D survivor game where the horde is made of garbage monsters. You fight off wave after wave, and sustainability quiz questions appear during play. Answer them, and the knowledge turns into power-ups that help you hold out against the growing horde.
The creator, a father of four daughters, wanted to make something fun that also has a positive influence on children. It was built with Codex on Three.js, supports online multiplayer, runs on phones as well as desktops, and placed 121st of 945 at Vibe Jam 2026.
Learning is tied directly to progression, since the quizzes are part of how your character gets stronger. The environmental theme runs through everything: trash is the enemy, and sustainability is how you fight back.
