head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Precision 3D platformer of narrow corridors, crates, and unforgiving jumps.

Execution · Pure Mechanics
A remixed arcade shooter testing reflex precision and learned scoring-chain systems.
Crash Bandicoot leans Execution (Pure Mechanics); Space Invaders Extreme 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.
Crash Bandicoot
Tight jumps on narrow paths punish slop
Space Invaders Extreme
Rhythm-paced dodging and precise shots at high speed
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Hazards are fixed patterns
Space Invaders Extreme
Invader formations are scripted patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Everything scripted and placed
Space Invaders Extreme
Power-up rounds vary slightly between runs
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Crash Bandicoot
Box routes and gem requirements are learnable
Space Invaders Extreme
Chaining flicker patterns and fever modes is deep score tech
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.
