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 fast reflex platformer about swinging through hazardous environments precisely.

Execution · Pure Mechanics
An explosively destructible run-and-gun starring parody action-movie heroes.
Alien Spidy leans Execution (Pure Mechanics); Broforce leans Execution (Pure Mechanics).
Alien Spidy leans a little harder on execution, though the gap is small.
Alien Spidy
Quick swinging and precise reflexes define every level
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.
Alien Spidy
Solo platformer with no adaptive opponent
Broforce
Enemies are dumb scripts
Broforce leans a little harder on variance, though the gap is small.
Alien Spidy
Hazards are fixed and learnable
Broforce
Random bro assignments and destructible chaos shake runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Spidy
Optimal pathing speeds collection runs
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.
