Yes, Tm, in PI the categories are a bit different because of the insane category. That doesn't mean that you have a different category every time. Just compare it with other accept and official levels.
Edit: completed and highscore! This is a goddamn good level, I have to say.
Thnx Jos. As I am new to the PI game, I don't really have the feeling yet of the difficulty of every lvl so I may be mistaken. Feel free to change it at any time.
