I really liked the premise of the rover finding fossils and gaining powerups from them! The controls were good, same for the animation (with a special mention to the very smooth rover's suspension). The music was also good, though it felt more like a "desert temple" kind of ambiance.
My biggest confusion came from some platforms that would barely lift up and I never really knew if I was missing a powerup or if I was supposed to perform a tricky jump. To add to the confusion, there's also a platform you have to power up twice to get to the end of its path.
I felt stuck for a while until I managed a jump I really didn't think was possible. Some rapid platforming followed and I found myself in front of another jump I wasn't sure I could make. I missed and sadly gave up when I saw I would had to restart from the beginning (I don't know if there was any other path I could have chosen instead).
If you can move the platforms in such a way to make it possible at a glance to know if a jump is possible or not, I think you will have a very enjoyable game! It's not missing much and I'm sad I couldn't see the other powerups. Keep at it!
