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
Rhythm FPS where every shot must land on the metal soundtrack's beat.

Execution · Pure Mechanics
A synesthetic on-rails shooter where lock-on fire becomes part of the trance soundtrack.
Metal: Hellsinger leans Execution (Pure Mechanics); Rez leans Execution (Pure Mechanics).
Metal: Hellsinger leans a little harder on execution, though the gap is small.
Metal: Hellsinger
shooting on the beat is the entire skill test
Rez
Lock-on targeting in time with the beat tests aim and rhythm
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Metal: Hellsinger
demons follow fixed behavior
Rez
Enemy waves are entirely scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Metal: Hellsinger
deterministic arenas
Rez
Fixed rail paths; nothing is hidden after one run
Metal: Hellsinger leans a little harder on optimization, though the gap is small.
Metal: Hellsinger
weapon choice and streak management for scores
Rez
Score chains and route choices reward memorized play
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.
