head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Optimising terror combos against scripted victims to maximise a points score per level.

Optimization · Pure Optimization
Sitcom puzzle game about rigging perfect prank chains around a fixed routine.
Naughty Bear leans Optimization (Pure Optimization); Neighbours from Hell leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Naughty Bear
Simple melee and chase inputs with low timing demands
Neighbours from Hell
Timing pranks between patrol windows
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Naughty Bear
Victim bears run scripted panic routines, never modelling you
Neighbours from Hell
The neighbour loops a fixed routine
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Naughty Bear
Bear patrols add mild unpredictability per attempt
Neighbours from Hell
Routine unknown on first attempt, then converges
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Naughty Bear
Maximising scare-point combos per level is a solvable puzzle
Neighbours from Hell
Sequencing pranks for maximum combo rating
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
