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
Solving fixed gravity-bending puzzles inside a deterministic nightmare.

Optimization · Pure Optimization
A fixed-camera horror puzzle game solved by methodical dual-world navigation and item sequencing.
Darq leans Optimization (Pure Optimization); The Medium 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.
Darq
Slow stealth walking; minimal timing demands
The Medium
Third-person movement and simple stealth; very low twitch demand
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Darq
Nightmare enemies patrol fixed scripted routes
The Medium
No adaptive opponents; Maw is a scripted threat
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Darq
Puzzle solutions hidden only until first discovery
The Medium
Some item locations hidden on first run
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Darq
Gravity-bending puzzle logic is the entire test
The Medium
Dual-world puzzle solutions are deterministic and fully learnable
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.
