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 · Practiced Mastery
Wordless action-adventure where you rearrange a broken mechanical world.

Execution · Practiced Mastery
A monochrome puzzle-platformer about a boy lost in limbo.
Hob leans Optimization (Practiced Mastery); Limbo leans Execution (Practiced Mastery).
Limbo leans a little harder on execution, though the gap is small.
Hob
Dodge-roll combat and platforming with moderate timing
Limbo
Tight platforming with trial-and-error.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hob
Creatures attack on fixed patterns
Limbo
Hazards are scripted.
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Hob
World secrets unknown until uncovered
Limbo
No randomness.
Hob leans a little harder on optimization, though the gap is small.
Hob
World-transforming puzzles and upgrade routing carry the game
Limbo
Puzzles have fixed solutions.
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.
