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 · Practiced Mastery
Rhythmic target-locking down fixed rails with learnable scoring routes.

Execution · Practiced Mastery
Retro ninja platformer that flips from linear levels into a time-hopping metroidvania.
Rez Infinite leans Execution (Practiced Mastery); The Messenger leans Execution (Practiced Mastery).
The Messenger leans a little harder on execution, though the gap is small.
Rez Infinite
Target locking on rhythm carries the score chase
The Messenger
cloudstep chains demand precise aerial control
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Rez Infinite
Rail enemies are fully scripted
The Messenger
enemies and bosses are fully scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Rez Infinite
Fixed sequences - nothing random after one run
The Messenger
deterministic level design
The Messenger leans a little harder on optimization, though the gap is small.
Rez Infinite
Scoring routes and chain patterns are learnable per area
The Messenger
upgrade economy and late-game route knowledge
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.
