SAMA is a 2D mining puzzle game, currently in development. You are the AI on board a spaceship that is being held to ransom by a pirate vessel. You have to control your on board aliens and send them to planets in your system to retrieve minerals and items that the pirate requires. There are plenty of enemies and puzzles in your way though, and you need to keep your whits about you to find everything you need.
This is a 360 view of our game in the Unity Editor, just to show how the scene is built up of different layers. Thought you might find it interesting how a 2D game looks internally.
