It took a bit of getting used to, but I really like the atmosphere you were going for! The planet physics were fun to mess around with, and the resource management side is a nice way to work in the theme.
I could definitely see this being expanded into a full game for sure. My only criticism is that there's no prompt that tells you that you can click on items to collect them, but it's not too hard to figure out on your own. I also noticed that sometimes when you respawn mid-flight you totally keep all your momentum from before.
