head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Execution · Pure Mechanics
Cave's hardest bullet hell, built on suicidal close-range scoring and merciless execution demands.

Execution · Pure Mechanics
A time-trial racer where flawless inputs over fixed tracks are everything.
Ketsui: Kizuna Jigoku Tachi leans Execution (Pure Mechanics); Trackmania leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Ketsui: Kizuna Jigoku Tachi
Point-blank chip harvesting in bullet storms, brutal physical ceiling
Trackmania
Pure input precision over deterministic tracks defines everything.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Ketsui: Kizuna Jigoku Tachi
Enemies follow fixed scripts
Trackmania
No opponent; ghost runs only.
Ketsui: Kizuna Jigoku Tachi leans a little harder on variance, though the gap is small.
Ketsui: Kizuna Jigoku Tachi
Deterministic patterns, trivial randomness
Trackmania
Tracks are deterministic with zero randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Ketsui: Kizuna Jigoku Tachi
Multiplier chip routing is a solved-route discipline
Trackmania
Line optimization and shortcut discovery matter heavily.
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.
