Exist personality mixes that make the video game difficult to end up?
I do not think so. Particular mixes will possibly make it harder, yet it appears you usually just need to require 1 personality's unique ability to triumph; Dave and also the 3rd personality can simply be bodies to do things every person can do.
I am theorizing based upon details from this walkthrough which has guidelines for triumphing making use of each personality's unique ability, and also merely calls your 3rd personality "your 3rd child."
The walkthroughs do state to pass by both Syd and also Razor (due to the fact that their abilities coincide ) yet they still do not end that the video game will certainly be irresistible with them.
That claimed, exterminating among your personalities can conveniently make the video game difficult.
