Loved the graphics!
Nothing else to add to the others comments, but I have something for you :D
I just had a bug. I jumped out of the rocket on a landing platform, but the rocket was still flying (I got out of fuel, so I hoped it will stop the rocket magically). But the rocket continued flying and crashed. So I reappered on the first platform with the rocket, but I wasn't able to go on the rocket anymore. And when I was moving or jumping, so did the rocket!
I could'nt make a bigger gif, but you have the idea here :)
