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

Execution · Practiced Mastery
Macabre Wonderland platformer where Alice slices through her own broken psyche chapter by chapter.

Execution · Practiced Mastery
A coin-obsessed 2D Mario built around hoarding a million coins.
Alice: Madness Returns leans Execution (Practiced Mastery); New Super Mario Bros. 2 leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Alice: Madness Returns
Float-platforming and weapon-switch combat ask moderate precision
New Super Mario Bros. 2
Standard 2D Mario jumping precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Alice: Madness Returns
Wonderland enemies attack on fixed tells
New Super Mario Bros. 2
Fully scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alice: Madness Returns
Hidden collectibles are one-time discoveries
New Super Mario Bros. 2
Fixed levels, known secrets
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alice: Madness Returns
Weapon upgrades and enemy counters are quickly mapped
New Super Mario Bros. 2
Coin-rush routing for maximum collection
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.
