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 dual-screen bullet-hell shooter testing aim and debris dodging.

Execution · Pure Mechanics
An arcade test of jump timing and enemy-flipping precision on a single screen.
Big Bang Mini leans Execution (Pure Mechanics); Mario Bros. leans Execution (Pure Mechanics).
Big Bang Mini leans a little harder on execution, though the gap is small.
Big Bang Mini
Stylus aiming and dodging falling debris demands precision
Mario Bros.
Precise jumps and bump timing under crowding enemies decide survival
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Big Bang Mini
Enemies follow fixed bullet patterns, not adapting
Mario Bros.
Versus mode adds light human interference, enemies are scripted
Big Bang Mini leans a little harder on variance, though the gap is small.
Big Bang Mini
Some patterned chaos but largely learnable
Mario Bros.
Enemy spawns vary slightly but patterns are quickly learned
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Big Bang Mini
Managing dual-screen risk-reward improves scoring
Mario Bros.
POW block usage and enemy routing have known best lines
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.
