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.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.

Execution · Pure Mechanics
A pointer-aim shooting gallery scored on accuracy and combo upkeep.
Half-Life 2 leans Execution (Pure Mechanics); Link's Crossbow Training leans Execution (Pure Mechanics).
Link's Crossbow Training leans a little harder on execution, though the gap is small.
Half-Life 2
Gravity gun and shooting demand precision.
Link's Crossbow Training
Pointer aim speed and accuracy are literally the whole game
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
Link's Crossbow Training
Targets and enemies follow set spawn patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Almost no randomness.
Link's Crossbow Training
Stages replay identically for score chasing
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Half-Life 2
Linear progression with no builds.
Link's Crossbow Training
Combo multipliers and spawn memorisation lift high scores
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.
