Astrominer

Astrominer is a minimalist space‑themed browser game built entirely with HTML and CSS.

Your mission is simple but critical: collect 10 unique elements from 10 different celestial bodies to save your home world from pollution. Each asteroid, moon or planet you visit holds one of the resources needed to restore balance back on Earth.

On this journey you’ll face threats such as incoming asteroids and hostile alien ships. You must read the field, avoid collisions and decide when to fight or when to maneuver out of danger.

Astrominer supports three ways to play:

• Solo mode – pilot your ship alone and handle navigation and survival by yourself.  

• Versus mode – confront other players and try to complete the objective before they do.  

• Co‑op mode – one player flies as the pilot while another takes the role of gunner, controlling the weapons to protect the ship during mining runs.

To make the game accessible for both children and experienced players, there are four difficulty levels:

Kids, Easy, Normal and Hard. Kids mode slows things down and reduces threats, while Hard mode turns the asteroid field and alien encounters into a much more demanding challenge.

There are no downloads or complex setups – Astrominer runs directly in your browser. If you enjoy space atmospheres, cooperative play and short, replayable missions, this game was made for you.
