head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Practiced Mastery
Neon top-down massacre where each floor is a one-mistake execution puzzle.

Execution · Pure Mechanics
A Build-engine shooter rewarding fast, precise gunplay and thorough level exploration to find secrets and supplies.
Hotline Miami leans Execution (Practiced Mastery); Ion Fury leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Hotline Miami
One-hit-death rooms demand flawless fast inputs
Ion Fury
Build-engine movement and precise gun skill define the combat ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Hotline Miami
Enemies are dumb scripted reactors
Ion Fury
All enemies are scripted with fixed attack and patrol routines
Ion Fury leans a little harder on variance, though the gap is small.
Hotline Miami
Slight enemy behavior wobble between restarts
Ion Fury
Level secrets and enemy ambushes are hidden on first run
Hotline Miami leans a little harder on optimization, though the gap is small.
Hotline Miami
Route planning and mask choice per floor
Ion Fury
Ammo conservation and alternate-fire choices reward systematic play
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.
