glynn, you don't need to download the music and speech, but they add a lot to the experience. i recommend downloading them if you have the bandwidth / patience.
rowan, all i meant by "catching" was that my experience has been, when the speed is high, the character starts moving and you see that he's about to fall off the beanstalk but don't have a chance to stop him before he falls off. slowing down the speed can help here. (i had this experience coming down from cloudland... not on the beanstalk, though! don't want to give anything away...)
glad you finally made it up!
