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
A reflex obstacle-course game about timing jumps and dodges through deadly stages.

Execution · Pure Mechanics
Brutal rhythm-violence game where perfect timing on a screaming track is all that exists.
Aztec Challenge leans Execution (Pure Mechanics); Thumper 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.
Aztec Challenge
Reacting to spears, traps and pits with precise timing wins
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.
Aztec Challenge
No adaptive opponent in a scripted obstacle gauntlet
Thumper
No opponent, only the track
Aztec Challenge leans a little harder on variance, though the gap is small.
Aztec Challenge
Some randomness in projectile timing
Thumper
Tracks are fixed and learnable
Thumper leans a little harder on optimization, though the gap is small.
Aztec Challenge
Pattern memorisation of each level underneath
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.
