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 · Light / Casual
Short narrative horror about a doomed freighter crew told in fractured time.

Variance · Light / Casual
An interactive story that tests emotional choice, not skill.
Mouthwashing leans Optimization (Light / Casual); The Walking Dead leans Variance (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Mouthwashing
Walking and simple interactions
The Walking Dead
Quick-time prompts are forgiving and rarely fail the story
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Mouthwashing
No opposition; it is a story
The Walking Dead
No opponent - characters follow the script
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Mouthwashing
Narrative surprises only on first viewing
The Walking Dead
Branch outcomes are hidden on a first playthrough only
Mouthwashing leans a little harder on optimization, though the gap is small.
Mouthwashing
Light puzzles guide a fixed story
The Walking Dead
Choices barely gate progress; nothing meaningful to solve
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.
