Hi, I’m Leandro Passos, a Brazilian hobbyist developer and space enthusiast.

I work in public administration and organizational planning, and in my free time I create small browser‑based games and digital artifacts inspired by aviation, astronomy and science.

Astrominer is one of these projects: a space‑mining HTML/CSS game where you collect 10 elements from 10 different celestial bodies to save a polluted world, facing asteroids and alien ships along the way. It supports solo play, competitive confrontations and a cooperative mode with one player piloting and the other acting as gunner, plus four difficulty levels ranging from Kids to Hard.

My goal is to build simple, accessible experiences that can run in a single browser tab and still feel like a small space adventure. If you enjoy what I’m making and want to encourage future experiments, optional donations are very welcome – they help keep the game online and support new space‑themed ideas.

Thank you for playing and supporting independent creators.
