It took me a while to understand the mechanic, at first, I thought I had to maneuver the jetpack between the planets. Liked planet art, also soundtrack fits pretty well as for me. Great job.

Huh, this is really neat! It's like a cross between a lunar lander (always a soft spot in my heart for those) and a gravity-based platformer. Took me a while to get the hang of it but I really enjoyed zipping around once I did! Would love to play a time attack or something with this mechanic.
