Pretty neat concept, I went a lot faster when I realized you can just ram into planets and satellites without dying. Getting to the packages is the hardest part but after that you can just floor it to the next planet. I Got 4 packages in.
I really love the presentation but I would've liked to see more things to do when moving from planet to planet, like maybe having to land carefully or dodge asteroids. As it stands though, it's a sweet game considering the time pressure. Nice job!
