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
Raw arcade reflexes against accelerating swarms with mild spawn randomness.

Execution · Pure Mechanics
Motion-controlled WarioWare where you snap the remote into poses to clear five-second microgames.
Millipede leans Execution (Pure Mechanics); WarioWare: Smooth Moves leans Execution (Pure Mechanics).
Millipede leans a little harder on execution, though the gap is small.
Millipede
Trackball precision under swarming pressure is everything
WarioWare: Smooth Moves
Instant motion-pose changes and gesture accuracy under pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Millipede
Enemies follow fixed movement rules
WarioWare: Smooth Moves
No adaptive opposition, just scripted prompts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Millipede
Spawn waves and DDT timing vary run to run
WarioWare: Smooth Moves
Random microgame draws keep each run unpredictable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Millipede
Mushroom-field management is a thin strategic layer
WarioWare: Smooth Moves
Learning every form and microgame solution converges
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.
