Another 5-9 attempt (gatling route) | Plants vs Zombies Minus

This strat is about focusing all on dps, gatlingpea is one of the most reliable with their chance to slow down zombies, problem is since there aren't any instakills other than squash, it means that now the ladder zombies will be a major problem due to the mini version of him that releases after losing his ladder, potentially eating all of my gatlingpeas and making the run cooked. I also had to mention that the start with this strat can be rng since a tanky zombie can just spawn in second wave. Again, if you got suggestions to beat this level i'll appreciate it.
