This was awesome! It was difficult to see at times in these caves, but I did enjoy the progressive upgrades every time I died. Felt like I was getting stronger! Poor Jeep took a heck of a beating, but I'm sure it'll be okay. I enjoyed jamming out the music as it seemed to get more and more chaotic with every level.
I was able to find that each time I failed a level and came back to it, I'd have the ability to free-form float around, as though gravity steadily rotated its way upwards. The more times I failed, the stronger my ability to float upwards aggressively, which meant some wild movements as I engaged in dogfights with the flying pebbles!
