I would say that it took me around 25 hours to get all 120 stars. I don't know if I want to ruin what happens at the end, or if you already know, but there's some replay value there. And it sort of does get harder, but some stages are harder than others, so it's a little uneven. But it gets crazier and crazier as it goes. And there's a bunch of hungry lumas everywhere, and other galaxies, so don't worry. And I'm sure you're not "done" with the first dome.
