One of if not the most interesting idea on the jam! The art style is also great!
Surprisingly this was also unironically the hardest game I played and was able to complete.
I would suggest showing the range for nearby stars on screen so the player can tell exatcly among which stars the constellation stars can be found. And there was also an issue once where I made the right constellation in the wrong order (went clockvise and not vice versa and it didn't count) which could be sooooo confusing when you're not sure about the shape.
One quality of life change that would be nice to see is the ability to reset the constallation phase wighout reseting the hint phase - what I mean is if I made the wrong contelation now, I have to manually unclick the start in the same order I clicked them so it would be cool to have the button that just clears the lines between stars without reseting the whole level.
I really enjoyed the game and hope you continue to work on it after the jam!
