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

Optimization · Pure Optimization
Solving fixed grim puzzles to escape a facility, dexterity-free.

Optimization · Pure Optimization
Hand-drawn puzzle where overlapping illustrated panels unlock impossible connections.
Cayne leans Optimization (Pure Optimization); Gorogoa 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.
Cayne
Isometric point-and-click, no dexterity
Gorogoa
Dragging panels requires no skill
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cayne
No adaptive threat in the facility
Gorogoa
No opponent exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Cayne
Story horrors are hidden until uncovered, then static
Gorogoa
Solutions unknown on first encounter only
Gorogoa leans a little harder on optimization, though the gap is small.
Cayne
Solving fixed environmental puzzles drives all progress
Gorogoa
Each panel arrangement has one elegant solvable answer
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.
