Observatory

this is a really cute idea and I hope you make more of it! the pixel art's really cute

I'd figure that you were meaning to add more constellations, but if you go back to the constellation after you've made it and go to the first star, you get trapped in this hell and can't escape:

so it probably makes sense to make copies of the first few rooms or smth and exit to them once you complete the constellation, and have the right exit redirect to the finished constellation room
