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

Optimization · Systems & Chaos
A match-three adventure testing chain planning against random board fills.

Optimization · Pure Optimization
Survival horror prequel built on swapping two characters with no item boxes.
Azkend 2: The World Beneath leans Optimization (Systems & Chaos); Resident Evil 0 leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Azkend 2: The World Beneath
Matching tiles needs only modest speed
Resident Evil 0
Tank-control combat is modestly demanding
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Azkend 2: The World Beneath
Solo with no opponent to predict
Resident Evil 0
Enemies follow fixed behaviour
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Azkend 2: The World Beneath
Board fills randomly, driving each match
Resident Evil 0
Hidden layouts surprise until mapped
Resident Evil 0 leans a little harder on optimization, though the gap is small.
Azkend 2: The World Beneath
Planning chains and power-up use is the skill layer
Resident Evil 0
Two-character item juggling makes routing the real game
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.
