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 · Twitch Chaos
Rapid-fire reflex bursts against randomised waves in ten-second chunks.

Execution · Pure Mechanics
The defining mobile endless runner of swiping past cliffs, roots, and flames at increasing speed.
Shutshimi leans Execution (Twitch Chaos); Temple Run 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.
Shutshimi
Ten-second waves demand instant dodging and target triage
Temple Run
Swipe reactions at ever-rising speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Shutshimi
Enemies spawn from random tables, not a mind
Temple Run
The demon monkeys never adapt
Shutshimi leans a little harder on variance, though the gap is small.
Shutshimi
Randomised waves and absurd power-ups reshape every run
Temple Run
Procedural track segments each run
Shutshimi leans a little harder on optimization, though the gap is small.
Shutshimi
Upgrade choices under time pressure are a thin layer
Temple Run
Powerup upgrades and segment recognition help
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.
