Great job with the rover. It controls really well, looks like a realistic vehicle, engine sounds fit well, too. Mars surface is a bit empty but it's exactly that I expected, so it's alright. Tutorial is well done, the game is easy to pick up and play, the objective is clear and I didn't have any technical issues.
The only issue I see with the game right now is lack of challenge. Maybe if the terrain was a little bit more difficult to navigate, it would be more fun.
Well done!
