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

Execution · Pure Mechanics
A frantic vertical roguelite about falling fast and shooting your boots.

Execution · Pure Mechanics
Pure reflex weaving through procedurally shuffled obstacle fields before sundown.
Downwell leans Execution (Pure Mechanics); Race the Sun 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.
Downwell
Gunboot timing and split-second landings decide runs
Race the Sun
Split-second weaving at ever-rising speed is the whole test
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Downwell
Enemies never adapt
Race the Sun
Obstacles never predict you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Downwell
Procedural wells and shop offers vary runs
Race the Sun
Procedural daily worlds keep layouts unknown
Downwell leans a little harder on optimization, though the gap is small.
Downwell
Combo lines and upgrade picks reward study
Race the Sun
Powerup priorities and scoring lines are quickly learned
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.
