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.

Execution · Pure Mechanics
A run-and-gun boss rush about dodging scripted patterns with tight inputs.

Execution · Practiced Mastery
A voxel-based arcade shooter where precise movement and optimal human-rescue sequencing drive score.
Cuphead leans Execution (Pure Mechanics); Resogun leans Execution (Practiced Mastery).
Cuphead leans a little harder on execution, though the gap is small.
Cuphead
Tight dodging and parry timing decide every boss.
Resogun
Precise overdrive timing and bullet-threading at high speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Cuphead
Bosses cycle scripted phases; no adaptation to player.
Resogun
Scripted enemy formations only
Resogun leans a little harder on variance, though the gap is small.
Cuphead
Minor attack-order shuffling between phases.
Resogun
Particle-based destruction and some randomised enemy entry points
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Cuphead
Loadouts and boss phase order are fully learnable.
Resogun
Keeper rescue sequencing and phase timing are 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.
