It's really hard to explain...anyways, one of the threads...in Help I think, has a map, check that... forget it, the map is tiny...all I can say is to go on youtube...
with the moving platforms...don't land on the edge of the last one...especially not when it's turning around and to stay on them better, press the opposite direction of the wall they hit (if they hit the right wall, press left)
which part of the stage are you having trouble with?
As for Dracula...if he uses the attack I've dubbed "Pearl" (two white balls)...watch them very closely so that you know where to move in order to not get crushed.
No, but it's not really that difficult to hit R every time you die...I do it. Which is why I say that this game taught me to find my 'R' key in the dark...
