guys, girls, you don't have to "roll" over the spikes. you can just run straight through any of those spikes in the floor sections... as long as you don't stop, the spikes won't come up till after you've crossed over them. you only have to time your run out to miss the back and forth spikey polls. it's very very simple. do not roll, that is not needed. just run right through there, very easy.
