I remember a comic too, but the original story is The Egg by Andy Weir. https://www.galactanet.com/oneoff/theegg_mod.html

If there is a comic and someone finds it, please link it.

Edit: found a comic by voldult on Webtoons, but that isn’t it. I remember a denser, darker style. Now I’m doubting my memory. Maybe I just read the story and imagined a comic based on the cover art?
