head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Practiced Mastery
Pixel-physics roguelite where every pixel is simulated and lethal.

Optimization · Practiced Mastery
Side-scrolling roguelike where item synergies snowball against a relentless difficulty clock.
Noita leans Optimization (Practiced Mastery); Risk of Rain leans Optimization (Practiced Mastery).
Noita leans a little harder on execution, though the gap is small.
Noita
Real-time platforming and aim under physical chaos.
Risk of Rain
Dodging projectiles and platforming under scaling pressure.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Noita
Scripted enemy AI.
Risk of Rain
Enemies spawn and chase; no adaptation.
Noita leans a little harder on variance, though the gap is small.
Noita
Procedural world and wand drops dominate runs.
Risk of Rain
Item drops and stage rolls dominate run identity.
Noita leans a little harder on optimization, though the gap is small.
Noita
Wand crafting and pixel physics reward deep mastery.
Risk of Rain
Item stacking and time-pressure routing is solvable.
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.
