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 · Pure Mechanics
An early arcade climber demanding tight, repeatable jump execution.

Execution · Pure Mechanics
House of the Dead rebuilt as a typing game where zombies die to fast accurate keystrokes.
Donkey Kong Junior leans Execution (Pure Mechanics); The Typing of the Dead leans Execution (Pure Mechanics).
The Typing of the Dead leans a little harder on execution, though the gap is small.
Donkey Kong Junior
precise vine-climbing and jump timing
The Typing of the Dead
Raw typing speed and accuracy wins
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong Junior
enemies follow fixed patrol patterns
The Typing of the Dead
Zombies follow scripted spawns
The Typing of the Dead leans a little harder on variance, though the gap is small.
Donkey Kong Junior
minor enemy timing variance
The Typing of the Dead
Random word prompts per zombie
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Donkey Kong Junior
minimal route memorization needed
The Typing of the Dead
Spawn patterns and boss prompts memorisable
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.
