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 physics construction puzzler about building cost-efficient structures to guide an armadillo.

Optimization · Pure Optimization
A perspective-rotation platformer with a hidden cryptographic layer that rewards patient decoding.
Armadillo Run leans Optimization (Pure Optimization); Fez 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.
Armadillo Run
Building structures has no twitch requirement
Fez
Rotation and platforming needs light precision only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Armadillo Run
No opponent; pure physics sandbox
Fez
No opponent; solo exploration puzzle
Armadillo Run leans a little harder on variance, though the gap is small.
Armadillo Run
Physics is deterministic once a structure is built
Fez
World is fixed and deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Armadillo Run
Designing efficient physics structures within budget is the whole game
Fez
Decoding the deep cipher system and spatial cube logic is the core challenge
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.
