head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A cinematic platformer testing traversal timing through fixed environmental puzzles.

Execution · Practiced Mastery
Kirby's breezy Game Boy debut, floating and inhaling through five short dreamlike stages.
Deadlight leans Execution (Practiced Mastery); Kirby's Dream Land 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.
Deadlight
Jump and vault timing under pursuit needs precision
Kirby's Dream Land
Gentle platforming, harder in Extra Mode
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deadlight
Shadows mob on simple fixed triggers
Kirby's Dream Land
Bosses loop tiny fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Deadlight
Linear cinematic levels with nothing random
Kirby's Dream Land
Nothing hidden after one loop
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Deadlight
Learning trap layouts and zombie luring solves each screen
Kirby's Dream Land
Short fixed levels, simple boss study
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.
