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
Hand-drawn puzzle where overlapping illustrated panels unlock impossible connections.

Optimization · Pure Optimization
Piecing together a scripted murder conspiracy from hidden clues.
Gorogoa leans Optimization (Pure Optimization); Post Mortem 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.
Gorogoa
Dragging panels requires no skill
Post Mortem
Point-and-click interface, zero dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
No opponent exists
Post Mortem
Suspects follow scripted dialogue trees
Post Mortem leans a little harder on variance, though the gap is small.
Gorogoa
Solutions unknown on first encounter only
Post Mortem
The conspiracy is hidden information revealed by investigation
Gorogoa leans a little harder on optimization, though the gap is small.
Gorogoa
Each panel arrangement has one elegant solvable answer
Post Mortem
Piecing fixed clues into the solution is the game
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.
