I know it's an old-ish game now but I just had to register my frustration with the final boss fight ('The Terrace' level). It was so bad that I installed the PC version and beat the game that way because the controls for the PSP were so dreadful. It was the second of the three stages that was so bad.

For the entire boss fight (unlike the rest of the game) you can't control the camera independently, so when the second stage starts you are being hit by moving objects coming from off screen that you have no way of seeing in advance. You can't line up your jumps correctly either; you run along walls instead of up them. Pressing the attack button if you do manage to run up the wall to jump towards the boss doesn't trigger the attack sequence, and when you land it is usually in the path of one of the moving objects you can't avoid.

Now a boss fight at the end of any game should be a challenge, and you don't expect to win at the first attempt. However, when you've had about 50 attempts and you still can't manage it, the problem is clearly not you but the game. After all, if you can make it all the way to the end, you should really have enough skill to finish the game.

On the PSP this is a disgraceful mess, made worse by the fact that if you die you have to complete the first stage of the fight again (which I can do no problem, taking virtually no damage, but it's utterly tiresome to be forced to repeat myself). I don't know if I'll bother to finish this now as it's getting so annoying. Caning across the bare buttocks is too good for the developers who coded this crappy sequence.

For purposes of comparison, I beat the whole sequence (on easy, because I was so fed up) at just the second attempt on the PC. I do love the PSP but when you come across something like this you can't help feeling shortchanged.
