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 · Practiced Mastery
Nintendo's branching rail shooter where score medals demand perfected routes.
Hotline Miami leans Execution (Practiced Mastery); Star Fox 64 leans Execution (Practiced Mastery).
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
Star Fox 64
Rail-shooter aim, barrel rolls, and boost timing are everything
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
Star Fox 64
Entirely scripted bosses and waves
Hotline Miami leans a little harder on variance, though the gap is small.
Hotline Miami
Slight enemy behavior wobble between restarts
Star Fox 64
Fully deterministic once routes are known
Star Fox 64 leans a little harder on optimization, though the gap is small.
Hotline Miami
Route planning and mask choice per floor
Star Fox 64
Medal scores and route branches reward total memorization
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.
