A very fun and creative puzzle game! Definitely got pretty stumped near the end but eventually managed my way through.
Of note however I did fine a single error, in the second to last stage I managed to solve the puzzle by only combining two of the stars in a particular formation while the other was on its own. I could not offer how to recreate the set-up due to the complexity of the puzzle but I am sure it's a quick fix.
All in all a very fun way to spend some time!
