I unfortunately had a very difficult time with this game. Even small movements of the mouse would spin the camera almost fully 360 degrees, and I couldn't figure out exactly what I was supposed to do? When I could wander around the planet I didn't see anything to interact with or do, besides avoiding the sun and the spider bots.
It is a very interesting premise, though, and I really like what you're doing with the planet's day/night cycle and walking around a small planet. I hope you keep working on it! ^_^
