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

Execution · Practiced Mastery
A hand-drawn western take on Hotline Miami where you cock the revolver before every single shot.

Execution · Pure Mechanics
An explosively destructible run-and-gun starring parody action-movie heroes.
12 is Better Than 6 leans Execution (Practiced Mastery); Broforce leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
12 is Better Than 6
One-hit deaths, manual cocking, fast top-down aim
Broforce
Run-and-gun reflexes amid constant explosions
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
12 is Better Than 6
Enemies are placed and scripted
Broforce
Enemies are dumb scripts
Broforce leans a little harder on variance, though the gap is small.
12 is Better Than 6
Unknown enemy placements on first attempts only
Broforce
Random bro assignments and destructible chaos shake runs
12 is Better Than 6 leans a little harder on optimization, though the gap is small.
12 is Better Than 6
Each room becomes a learnable clear order
Broforce
Knowing each bro's kit and level layouts helps
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.
