head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
Sitcom puzzle game about rigging perfect prank chains around a fixed routine.

Optimization · Pure Optimization
A physics puzzle game about building wobbly towers and bridges from living goo balls.
Neighbours from Hell leans Optimization (Pure Optimization); World of Goo 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.
Neighbours from Hell
Timing pranks between patrol windows
World of Goo
Placing goo balls needs only mild precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Neighbours from Hell
The neighbour loops a fixed routine
World of Goo
No opponent exists
Neighbours from Hell leans a little harder on variance, though the gap is small.
Neighbours from Hell
Routine unknown on first attempt, then converges
World of Goo
Physics are visible and deterministic
World of Goo leans a little harder on optimization, though the gap is small.
Neighbours from Hell
Sequencing pranks for maximum combo rating
World of Goo
Tower structure and goo economy are solvable per level
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.
