Obligatory comment on the stunning audio, art, and graphics, I just want to stare at it all day long, it's so amazing! (coming from a guy who can only draw triangle shapes haha)
That aside, and if you'd accept some constructive criticism, I feel like the main mechanic here is out of focus. That central focus: timing your impulse to bounce from planet to planet on the way out from the center, I'm just not seeing that explored in a fun way with the gameplay here.
I know from the comments below that you are ready to do some tweaking, but before you just start changing those variables in the script I'd ask you to take a step back and look at the design holistically, and really try to refocus and nail down what you are going for here. It's very easy to lose sight of that, especially when working on a large project with a big team.
All that said, I'm still astounded you accomplished this much in the 48 hours, and I look forward to seeing the updated version!
