Nice thought experiment, quite well done. The fact, that the graphics don't behave pixel perfect triggers me a little :D I loved the fact, that a day is actually a full rotation of the sky, that's a neat detail!
Thank you! I had a hard time thinking about the pixels with all the rotation--especially the player walking around the asteroid kinda bugs me too because he goes ever so slightly into the asteroid around the corners. Still, I'm glad that overall it looks pretty nice!
