Simple enjoyable game, and some very evocative descriptions :)
Two quick technical comments.
I think the game would be a lot easier to play if you had it open in a full window by default. It’s pretty crowded in the little Itch window. I opened it in a new tab, but not everyone will know how to do that.
Second, you have a nice starry background, but you attached it to body, and the body is pretty much invisible in a Sugarcube story. If you put the background on html instead, then you can actually see it.
