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

Optimization · Pure Optimization
A cryptic metroidvania puzzle-platformer set in a luminous animal labyrinth.

Optimization · Pure Optimization
The co-op sequel where two players engineer overlapping trap gauntlets against orc waves.
Animal Well leans Optimization (Pure Optimization); Orcs Must Die! 2 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.
Animal Well
Platforming precision moderate.
Orcs Must Die! 2
Co-op shooting and trap triggering
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Animal Well
Creatures follow scripted patterns.
Orcs Must Die! 2
Scripted wave pathing
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Animal Well
Hidden secrets to discover.
Orcs Must Die! 2
Endless mode shuffles compositions slightly
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Animal Well
Metroidvania puzzles reward deep optimization.
Orcs Must Die! 2
Upgrade spirit economy and trap synergies dominate
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.
