I really enjoyed the art style of the game, but the gameplay was quite boring. The rover moves a bit too slow in my opinion and there is not much to do. Once you scanned some rocks, and recharged your battery, you had to move a long empty way back without doing anything but holding the D key.
The music was well chosen for this project and the sound effects were nice (altough a bit loud, but that is just personal preference to me).
I personally really like space-exploration themed games, so I hope that you continue development as I see the potential with the concept!
