has anyone actually managed to get gold stamps on the bonus levels?

[zingar]

so far im already on chapter 3 getting gold stamps, (doing time trials only ATM) but decided to see the new bonus levels....

needless to say it was frustrating enough JUST to beat them. i cant imagine how hard itd be to get a time trial or survival gold stamp on these levels. (limited rotations might not be SO hard since after dieing the count goes back to what it initially was at the checkpoint)

anyways if you have then please reply :P
