It really isn't - there are ways to skip the entire 3rd platform, skip killing dumm dumm and skip doing the zombie maze. You basically just have to do the 2nd platform partly, do the bridge between dumm dumm and zombies legit, the bridge between zombies and bunnies + the last island with stuns/roots/slows + 50/50 bridge.
But tbh the only annoying jumps in that entire maze are the barrels. Everything else is doable in a very consistent manner the regular way too.
