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
First-person physics platformer about leaping across a convoy of crashing trucks.

Execution · Practiced Mastery
A neo-noir one-hit-kill action platformer about planning and replaying perfect assassinations.
Clustertruck leans Execution (Pure Mechanics); Katana ZERO leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Clustertruck
Frame-tight jumps across moving trucks
Katana ZERO
One-hit-death slashing and deflects demand precision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Clustertruck
No opponent
Katana ZERO
Enemies follow fixed placements and behaviours
Clustertruck leans a little harder on variance, though the gap is small.
Clustertruck
Physics chaos makes truck piles unpredictable
Katana ZERO
Rooms are identical on every attempt
Katana ZERO leans a little harder on optimization, though the gap is small.
Clustertruck
Route lines and ability use for speedruns
Katana ZERO
Planning the perfect room-clear sequence
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.
