It's impossible to jump over the yellow parts. Is it what we're supposed to do ?
The yellow zones within the mazes should be avoided, a true dead end if you will haha. Treat them as any other dead end but make sure to take note of where they are since they won't show up on your in game map the same way a regular dead end will and could easily catch you by surprise if you're using the map while walking too much. Also I recommend quicksaving often, hope this helps you in your search for the exit, thank you for playing!
