The graphics are decent. The concept is really great. Movement mechanisms seem to work and this definitely fits the theme, the problem is that the power runs out much too fast to do much. Adding music would help a lot.

The text is hard to read and the graphics aren't very pleasant to look at.

The movement speed is agonizingly slow. Realistic maybe, boring also. Didn't get far as the energy ran out already on the second rock. That was that.

The concept of controlling a rover in a hostile environment is solid. Your take on it is less than solid. Sorry to say.
