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 · Practiced Mastery
A metroidvania testing boss-pattern execution and ability-loadout planning.

Execution · Practiced Mastery
An action adventure rewarding combat timing against scripted boss patterns.
Ender Magnolia: Bloom in the Mist leans Execution (Practiced Mastery); God of War Ragnarok leans Execution (Practiced Mastery).
Ender Magnolia: Bloom in the Mist leans a little harder on execution, though the gap is small.
Ender Magnolia: Bloom in the Mist
Boss dodge timing and aerial control gate progress
God of War Ragnarok
Parry timing and combo execution in combat
God of War Ragnarok leans a little harder on reads, though the gap is small.
Ender Magnolia: Bloom in the Mist
Bosses cycle scripted attack patterns
God of War Ragnarok
Bosses use fixed movesets
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Ender Magnolia: Bloom in the Mist
The map is fixed, just unexplored at first
God of War Ragnarok
Negligible randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ender Magnolia: Bloom in the Mist
Ability loadouts, upgrades and route knowledge shape the run
God of War Ragnarok
Build choices and moveset mastery solve bosses
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.
