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
A perspective-rotation platformer with a hidden cryptographic layer that rewards patient decoding.

Optimization · Pure Optimization
A 3D factory-building puzzle where spatial reasoning and throughput efficiency are the entire challenge.
Fez leans Optimization (Pure Optimization); Infinifactory 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.
Fez
Rotation and platforming needs light precision only
Infinifactory
Block placement has no timing pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fez
No opponent; solo exploration puzzle
Infinifactory
No opponent; alien factory puzzle game
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Fez
World is fixed and deterministic
Infinifactory
Build targets are fixed and deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fez
Decoding the deep cipher system and spatial cube logic is the core challenge
Infinifactory
Engineering 3D factory lines that assemble alien products correctly and efficiently
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.
