Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.
Alpha Runner
Execution · Pure Mechanics
An endless-running arcade platformer.
Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
Alpha Runner leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
Alpha RunnerHalf-Life 2
Axis by axis
Execution6 vs 6
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Alpha Runner
endless-runner timing and reflex demands
Half-Life 2
Gravity gun and shooting demand precision.
Reads0 vs 1
Half-Life 2 leans a little harder on reads, though the gap is small.
Alpha Runner
no opponent, solo runner experience
Half-Life 2
Combine AI scripted, non-adaptive.
Variance2 vs 1
Alpha Runner leans a little harder on variance, though the gap is small.
Alpha Runner
obstacle patterns vary procedurally
Half-Life 2
Almost no randomness.
Optimization3 vs 3
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alpha Runner
route memorization for high scores
Half-Life 2
Linear progression with no builds.
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.
