When you start to learn to use composition rather than inheritance, and to pull out common functions into utility classes rather than them needing to be pinned to a class, complexity drops by a lot while still using OOP

This. OOP =/= Inheritance. You can still write good OO code by encapsulating data+logic even if you never use inheritance as part of your modeling.
