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

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

Execution · Pure Mechanics
A procedural bullet-hell shooter testing dodging and aim across endless waves.
Downwell leans Execution (Pure Mechanics); Really Big Sky 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
Really Big Sky
Dodging dense bullet hell and aiming decides survival
Really Big Sky leans a little harder on reads, though the gap is small.
Downwell
Enemies never adapt
Really Big Sky
Enemies follow scripted patterns, not adapting
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
Really Big Sky
Procedural enemy waves and hazards add chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Downwell
Combo lines and upgrade picks reward study
Really Big Sky
Drill timing and upgrade choices reward planning
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.
