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

Optimization · Pure Optimization
Sci-fi thriller played as the station AI solving its own crisis.

Optimization · Practiced Mastery
An on-rails photography game of capturing creatures in an abandoned park.
Observation leans Optimization (Pure Optimization); Penko Park leans Optimization (Practiced Mastery).
Penko Park leans a little harder on execution, though the gap is small.
Observation
Camera control and interface manipulation
Penko Park
Timing photo snaps but no demanding twitch ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Observation
Events are fully authored
Penko Park
Creatures follow scripted behavior, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Observation
Mystery unknown until uncovered
Penko Park
Creature appearances have mild randomness
Observation leans a little harder on optimization, though the gap is small.
Observation
Systems puzzles and station schematics solving
Penko Park
Learning creature triggers and routing for shots rewards planning
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.
