Building comparison
head to head
Alien SpidyvsMario Bros.
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Alien Spidy
Execution · Pure Mechanics
A fast reflex platformer about swinging through hazardous environments precisely.
Mario Bros.
Execution · Pure Mechanics
An arcade test of jump timing and enemy-flipping precision on a single screen.
Alien Spidy leans Execution (Pure Mechanics); Mario Bros. leans Execution (Pure Mechanics).
Alien SpidyMario Bros.
Axis by axis
Execution8 vs 7
Alien Spidy leans a little harder on execution, though the gap is small.
Alien Spidy
Quick swinging and precise reflexes define every level
Mario Bros.
Precise jumps and bump timing under crowding enemies decide survival
Reads0 vs 1
Mario Bros. leans a little harder on reads, though the gap is small.
Alien Spidy
Solo platformer with no adaptive opponent
Mario Bros.
Versus mode adds light human interference, enemies are scripted
Variance2 vs 2
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Alien Spidy
Hazards are fixed and learnable
Mario Bros.
Enemy spawns vary slightly but patterns are quickly learned
Optimization4 vs 4
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
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.
