i found the falling platform cassette to be rather fine, you don't need to rotate the camera as the distant platforms you need to get to line up with your dashes (fortunate that the dash doesn't have to face the camera unlike some other game)
in fact, the only times i recall needing to rotate the camera in a cassette stage were in spots where i wasn't in any rush
never found the dash to be too much of a problem as the level design is built around its limitations, definitely takes getting used to though
