head to head
Neither is simply harder - they are hard in different places. Bolsomito demands more variance; Marvel's Spider-Man demands more execution.

Execution · Light / Casual
A satirical Brazilian political-themed arcade game.

Execution · Practiced Mastery
Open-world superhero game whose joy is fluid web-swinging and rhythmic combat.
Bolsomito leans Execution (Light / Casual); Marvel's Spider-Man leans Execution (Practiced Mastery).
Marvel's Spider-Man leans clearly harder on execution.
Bolsomito
basic reflex-based arcade inputs
Marvel's Spider-Man
swinging flow and combat dodge timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bolsomito
no adaptive opponent present
Marvel's Spider-Man
thugs and bosses follow fixed patterns
Bolsomito leans clearly harder on variance.
Bolsomito
random comedic event triggers
Marvel's Spider-Man
open world is fully discoverable
Marvel's Spider-Man leans clearly harder on optimization.
Bolsomito
minimal solvable systems present
Marvel's Spider-Man
gadget loadouts and suit mods are shallow but present
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.
