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
An explosively destructible run-and-gun starring parody action-movie heroes.

Execution · Pure Mechanics
A bullet-hell action-adventure testing dodging and platforming precision through hostile arenas.
Broforce leans Execution (Pure Mechanics); Luna Abyss leans Execution (Pure Mechanics).
Luna Abyss leans a little harder on execution, though the gap is small.
Broforce
Run-and-gun reflexes amid constant explosions
Luna Abyss
Bullet-hell dodging and platforming demand precise inputs
Luna Abyss leans a little harder on reads, though the gap is small.
Broforce
Enemies are dumb scripts
Luna Abyss
Enemies are scripted, not adapting to you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Random bro assignments and destructible chaos shake runs
Luna Abyss
Some randomness in bullet patterns and encounters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Broforce
Knowing each bro's kit and level layouts helps
Luna Abyss
Weapon and movement mastery reward planning
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.
