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

Execution · Pure Mechanics
A reflex test of paddle precision against accelerating ball physics.

Execution · Pure Mechanics
VR Half-Life where hand-presence interaction defines every fight.
Arkanoid: Doh It Again leans Execution (Pure Mechanics); Half-Life: Alyx 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.
Arkanoid: Doh It Again
Paddle precision under accelerating ball speed is everything
Half-Life: Alyx
VR aim, reload, and grab inputs intense.
Half-Life: Alyx leans a little harder on reads, though the gap is small.
Arkanoid: Doh It Again
No opponent - bricks do not adapt
Half-Life: Alyx
Combine and headcrabs scripted.
Arkanoid: Doh It Again leans a little harder on variance, though the gap is small.
Arkanoid: Doh It Again
Power-up drops and ball angles add bounded randomness
Half-Life: Alyx
Resource and encounter variance light.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Arkanoid: Doh It Again
Brick-clearing order and power-up choices have known answers
Half-Life: Alyx
Few systems to tune.
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.
