Annoying experience in Super Mario Galaxy

I was playing some Super Mario Galaxy after yet another grueling day of reading Masters dissertations. I decided to start with the 'secret' star on the second level of the Toy Box galaxy, which involves going to a secret planet and turning all the blue question mark panels into yellow exclamation point panels and then picking up the star you're allowed to get once you do so.

I find this particular part of that level annoying because I find the game's camera very annoying in this particular spot. (I find it annoying in some other spots as well, but this one really irks me. In fact, the parts where the game's camera goes a bit nuts make me dizzy in real life when I play them. This is one of the spots in the game that does that.) OK, so I fought the camera and turned all the blocks in a way that would make Q*Bert proud and then I tried to make my way to the star (while fighting the camera again). Certain spiky platforms no longer move after all the blocks are turned. I got greedy and decide to get some star bits and I accidently bumped into the edge of a non-moving spiky platform because of my carelessness. The deflection from this knocked Mario prone in between two of the turned platforms. He tried to get up, but was caught in between so automatically ended up prone again. This turned out to be an infinite loop, as no form of jumping registered. Fuck. I thus needed to leave the level without my coveted star, and now I'll need to redo my efforts for this particular star. Bloody Hell! I'm not doing it now though because I play such games to reduce frustration, not to add to it. I'm just going to go read or something, but this will be pleasure reading rather than another dissertation.
