head to head
140 asks more than Half-Life 2, and the gap is execution.

Execution · Pure Mechanics
A minimalist rhythm platformer where abstract shapes and hazards pulse in lockstep with the soundtrack.

Execution · Pure Mechanics
Landmark FPS built on physics puzzles and tight gunplay.
140 leans Execution (Pure Mechanics); Half-Life 2 leans Execution (Pure Mechanics).
140 leans clearly harder on execution.
140
Jumps must land on the musical beat precisely
Half-Life 2
Gravity gun and shooting demand precision.
Half-Life 2 leans a little harder on reads, though the gap is small.
140
No opponent exists
Half-Life 2
Combine AI scripted, non-adaptive.
Half-Life 2 leans a little harder on variance, though the gap is small.
140
Fully deterministic rhythm patterns
Half-Life 2
Almost no randomness.
140 leans a little harder on optimization, though the gap is small.
140
Learning each sequence's timing solution
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.
