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

Optimization · Light / Casual
An underwater sci-fi horror about consciousness and identity.

Optimization · Light / Casual
A short narrative drive testing curiosity about branching endings, not driving skill.
SOMA leans Optimization (Light / Casual); Wheels of Aurelia leans Optimization (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
SOMA
Light stealth, gentle inputs.
Wheels of Aurelia
Steering is loose and outcomes barely depend on it
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
SOMA
Creatures follow scripts.
Wheels of Aurelia
Dialogue characters are authored, not adaptive
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
SOMA
Some hiding spot variation.
Wheels of Aurelia
Sixteen endings are hidden until routes are replayed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
SOMA
Few systems to optimize.
Wheels of Aurelia
Mapping which choices and routes trigger endings is light puzzle work
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.
