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

Execution · Practiced Mastery
Sequel platformer that swaps genres per level but always tests the hands.

Execution · Pure Mechanics
A punishing western arcade shooter testing directional-fire dexterity.
Earthworm Jim 2 leans Execution (Practiced Mastery); Gun.Smoke leans Execution (Pure Mechanics).
Gun.Smoke leans a little harder on execution, though the gap is small.
Earthworm Jim 2
Varied set-piece levels demand precise control
Gun.Smoke
Three-way shot aiming under relentless scroll pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Earthworm Jim 2
No adaptive opposition
Gun.Smoke
Outlaws spawn in fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Earthworm Jim 2
Deterministic levels and gimmicks
Gun.Smoke
Item barrels sit in the same spots every credit
Earthworm Jim 2 leans a little harder on optimization, though the gap is small.
Earthworm Jim 2
Learning each surreal level's fixed solution
Gun.Smoke
Boss patterns and item routes reward memorisation
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.
