Well they do, just...sometimes you dont see all of the layers, so if your screen sees just platforms and pikes, it may switch between ladders and bounces-which you dont see the change since...well, you dont see those two...
Yea, i have tried to make it so there is at least one element of each on screen most of the time (hence the starting level upper layer composition, where it all repeats, to help you understand whats going on), but its not always logical and i didnt have whole lot of time anyway
