I really like what you have going here!
I enjoy the spacey mood set by the minimal graphics and sound. It really fits well with the dangerous scifi feel to the gravity mechanic. And it the jam's theme is nailed with the limited area and the danger you can build up in there.
I think a smooth camera would have done a lot to improve the experience. The camera moving glued to the player like that makes it feel a bit jerky and disorienting.
I hope you keeping working on this past the jam/ With a little more time and polish I think there's something really good here!
