We did a quick prototype of a space shooter game that is designed to run well in browsers. The player collects a bright stones while flying through the asteroids field. It gives points that helps to unlock next ships. It is a classic idea for the game but we gave it a modern feel and realistic graphics. Our main goal was to publish it on the Crazy Games site. And we did exactly this:
