You have no clue about that and never will.I really don't understand why KsT doesn't invest into a better coder, who could try at least to optimize this mess. His next game will suffer from the same issues as The Twist. Doesn't matter if he use Unity 2020 or not. Resource-management is one of the most important things you have to keep an eye on, if you use Unity as game engine.
The next game is gonna be made a whole new way the twist was his first game and the next one he has learned a lot and is made a different way.
