Biodomes

Biodomes is a side-scrolling shooter named after the habitats designed to sustain the remaining human population. These habitats are incomplete and require various minerals for their completion, which players are tasked to collect and deliver.

The game features levels that scroll both left and right. Players control a spaceship, which must combat continuously spawning aliens. Defeated enemies drop materials that players can collect and deliver to designated zones corresponding to the material's color. To deliver materials, the spaceship must be positioned directly above the delivery zone, where a button press drops the material straight down. The spaceship operates using the Asteroids control scheme (rotating the ship left and right and using a button to thrust) without inertia.

In addition to minerals, defeated enemies drop powerups such as weapon upgrades, an enemy-freezing ability, smart bombs that destroy all objects on screen, auto-fire capabilities, extra shield energy, and temporary invincibility. Being hit by enemies or their projectiles reduces the ship's shield energy. Progress can be saved at any time.
