Envoy is a short physics based spaceflight game where you have been created by a monolith for the sole purpose of retrieving "force crystals" to it.
Weave and dodge around asteroids by utilizing realistic space physics, and have your flight somewhat regulated by a slight drag force applied when going too fast.
As you retrieve force crystals, you will unlock new abilities to utilize to make your mission easier. You can use them to outwit the locals, avoid an asteroid collision, or just accelerate the speed of your mission.
Once the mission is complete, you have only one objective: survive. Utilize abilities and the skills you have learned to fight even more aggressive locals, as they throw their most powerful forces your way.
