Thanks for the comment, I really appreciate the feedback!
The intent with the "do what you feel like" mechanics was to make making decisions feel more, "intuitive/contemplative" as I've been reading a lot of tarot/oracle-deck based games. Though I totally get what you're saying! "Roll a d8+2" works really well for picking a number of stars, especially if you want to mostly just use the generator or are trying to make a large group of constellations in a shorter amount of time.
