When you do not know where to run (on the wall), then a scratch will be visible on the wall sometimes. This is the right direction.
If you do not have a second sword, and there is a ledge and a couple of enemies, then it’s easier for a paired turnip throw them from there. This is done like this: we go to the enemy we press E, again E and (!!!!) Very fast arrows indicate the path of the flight (in the case of the breakdown) and all. BUT! With a black prince will not work.
