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
Arcade run-and-gun whose one-credit clears demand total spawn memorization and twitch.

Execution · Pure Mechanics
A precision movement game disguised as a card-action roguelite, decided almost purely by execution.
Metal Slug 3 leans Execution (Pure Mechanics); Neon White leans Execution (Pure Mechanics).
Neon White leans a little harder on execution, though the gap is small.
Metal Slug 3
one-hit deaths demand frame-level dodging and aim
Neon White
Card-discarding movement tech is the entire game at maximum precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Slug 3
every enemy wave is scripted
Neon White
Solo time-trial levels; no opponent to read or predict
Metal Slug 3 leans a little harder on variance, though the gap is small.
Metal Slug 3
branching paths vary runs slightly
Neon White
Fixed levels with no randomness; entirely deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Metal Slug 3
memorizing spawns is the path to a one-credit clear
Neon White
Route optimisation and card-discard sequencing form the depth layer
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.
