Half-Life 2
Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
The Impossible Game

Tests frame-tight jump timing through fully memorisable obstacle sequences.
Half-Life 2 leans Execution (Pure Mechanics); The Impossible Game leans Execution (Pure Mechanics).
Half-Life 2The Impossible Game
Axis by axis
Execution6 vs 9
The Impossible Game leans clearly harder on execution.
Half-Life 2
Gravity gun and shooting demand precision.
The Impossible Game
One mistimed jump restarts the level - perfect inputs win alone
Reads1 vs 0
Half-Life 2 leans a little harder on reads, though the gap is small.
Half-Life 2
Combine AI scripted, non-adaptive.
The Impossible Game
Solo - nothing to predict
Variance1 vs 0
Half-Life 2 leans a little harder on variance, though the gap is small.
Half-Life 2
Almost no randomness.
The Impossible Game
Levels are identical on every attempt
Optimization3 vs 5
The Impossible Game leans clearly harder on optimization.
Half-Life 2
Linear progression with no builds.
The Impossible Game
Memorising the jump sequence is half the climb
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.
