The aesthetics are great. Really cohesive. I especially like the crt effect. Audio is also looking nice. The spacey feeling of the music adds up to the atmosphere. I like how balance of jumping how often you jump between other planets and how often you have to refuel.
I guess that I would have two suggestions. The first would be to add a bit more feedback to the jumping. Maybe like a screenshake. Since you're doing this action all the time, it could even further improve the feel of the game. The other thing is that sometimes I felt really inconsistent with my gameplay. There were times when I didn't get any jump 6 times in a row and times when I got a score above 5k. Maybe making the first jump easier would help in making it all a bit smoother. For example you could slightly steer the player towards the ring that they're aiming.
