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
A tactile toy-box puzzler testing playful experimentation with hidden mechanisms.

Optimization · Pure Optimization
Claymation point-and-click adventure sculpted entirely from plasticine whimsy.
Gnog leans Optimization (Pure Optimization); The Neverhood 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.
Gnog
Poking and spinning toy heads requires no dexterity
The Neverhood
Point-and-click; no dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gnog
The toys are charming clockwork, not minds
The Neverhood
No opposition exists
Gnog leans a little harder on variance, though the gap is small.
Gnog
Each head's mechanisms are unknown until fiddled with
The Neverhood
Puzzles hidden until discovered, then fixed
Gnog leans a little harder on optimization, though the gap is small.
Gnog
Discovering each contraption's interaction sequence is the puzzle
The Neverhood
Adventure puzzle chains with single solutions
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.
