I hear some people complaining about the framerate. Are these problem on PS3/360?
There's a little framerate jerkiness in the later stages on PS3 (particularly the clock tower), but it's smooth as butter for most of the game.
The biggest issues I've run into are a few occasions where the narrator gets cut off, some voice/music balancing issues during the ending, and the inability to skip boss intro cutscenes (again, mostly just the final boss, since I died to her a good 7 or 8 times and had to go through the entire intro sequence every single time I restarted the fight).
Also, if you die and restart at a checkpoint, any collectibles you found prior to that checkpoint seem to get reset, so if you want to unlock everything, you pretty much have to beat each stage on one life.
These are all pretty minor complaints, though, in an otherwise amazing game. I had no control issues, I didn't feel like the game was too hard, and really... I enjoyed just about every minute of it!
