I was initially confused as to how it met the them and was ready to be critical of it, as I was just landing on the ground for the first few jumps. In almost a No Man's Sky-esque way, though, the game opened up to be a lot bigger than I thought with the upgrades. Seriously, the dynamic change in music as the view got bigger was a great design choice.
I've played games like this before, and this was an excellent take on the genre. The theme helped this, and you interpreted it in a great way. I actually found myself playing this one for way too long and had to move on. Great job!
My only criticism is maybe the sharp sounds used for the boosts and teleportation.
