liked it a lot! i did a 100% run which i don't think i'll repeat - the blue coins are a fun idea in theory (even if you're stuck on a shine you can still make some incremental progress exploring the area) but kind of frustrating and tedious to collect all of. there was only really one 'infamous' shine i had trouble with, the one you have to reach the island with yoshi for: because getting there at all is difficult, and then doing the shine is difficult, it meant that i had to replay one long annoying preliminary section every time i got a game over which was uh...several times. so i definitely had my frustrations with this game...overall i think i like super mario galaxy more, but i still found this one a satisfying experience, and especially i just really loved moving around the place in it? that's probably the thing i'm going to miss the most. also: banging sountrack
