I’m up to 68 stars in Super Mario Galaxy now, and am mostly finished the cluster of galaxies I’m in right now. I think there’s one more cluster though, even though it doesn’t appear on the main map, since I can see another hut where you enter galaxies off in the distance and there’s what looks like an inactive transfer point to it.

Of particular note today was the Toy galaxy, where Mario gains a spring powerup that turns him into something like a slinky, with the ability to bounce really high. It’s a bit difficult to control though, since you never stop bouncing around, but that’s probably supposed to be part of the challenge…

It was particularly frustrating in this one section where there’s a cylinder with multiple levels of brick platforms inside. Getting to the top takes a bit of precision, but if you hit the bottom of a platform when you bounce (which is really easy in the tight space), you break the bricks, making it harder to stay on that platform. The longer you work at it, the harder it gets, as you get less and less landing space to work with. It must have taken me a good 15-20 minutes just to get to the top, and to make things worse, it turned out to be a completely optional area and the reward was just some extra star bits. :P
