After climbing for a while, these stages can actually be a bit disorientating. Basically, there are sometimes platforms. And he auto-walks on them. It's crazy, especially after you haven't seen any platforms for the whole game. But they quickly become just as challenging as climbing the tower. The monkey will automatically move forward, but can also have his direction changed by - you guessed it - double jumping. This also kind of limits you jumping height in these stages, forcing you to be smarter with your moves.
