This was an interesting concept of a game. I liked the different scenarios and the choices you presented, and it was certainly a strange place. It's a shame there was only one level and some of the choices given in each level were repeated, so if you picked the correct one then you knew what to do when you hit it again.
I'm not sure the 3D exploration format was the best for this game. There was some good environment on the planet but with no animation moving from square to square felt clipped. The writing and theming was the core of the game so a 2D or point and click style may have suited better.
