Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Practiced Mastery
A traditional licensed platformer testing jump timing across fixed, memorisable levels.

Execution · Practiced Mastery
Precision sniping and arena navigation through fixed, gimmick-laden levels.
