Don't thank me, thank friend-of-RPS Sam C, for today's wonderful puzzle game. And you will thank her, because this is joyful.
Hoshi Saga is by Japanese developers Nekogames, it's a series of completely charming puzzles based around finding the star. Little more needs to be said - just go play. And then come back here to thank Sam, and then yell at her because you're stuck and really frustrated.
