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
Synesthetic rail shooter where shooting on the beat scores a psychedelic symphony.

Execution · Pure Mechanics
Brutal rhythm-violence game where perfect timing on a screaming track is all that exists.
Child of Eden leans Execution (Pure Mechanics); Thumper leans Execution (Pure Mechanics).
Thumper leans a little harder on execution, though the gap is small.
Child of Eden
Lock-on rhythm targeting and dodge precision
Thumper
Split-second rhythm inputs at speed are the entire test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Child of Eden
Enemies follow choreographed waves
Thumper
No opponent, only the track
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Child of Eden
Deterministic stage choreography
Thumper
Tracks are fixed and learnable
Child of Eden leans a little harder on optimization, though the gap is small.
Child of Eden
Score routes and memorised wave patterns
Thumper
Memorizing patterns and scoring lines helps mastery
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.
