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

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

Execution · Pure Mechanics
An endless arcade runner testing reflexes against scrolling hazards.
Downwell leans Execution (Pure Mechanics); Nyan Cat: Lost In Space leans Execution (Pure Mechanics).
Downwell leans a little harder on execution, though the gap is small.
Downwell
Gunboot timing and split-second landings decide runs
Nyan Cat: Lost In Space
Precise dodging and platform timing decides survival
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
Nyan Cat: Lost In Space
No opponent to predict; scripted hazards
Downwell leans a little harder on variance, though the gap is small.
Downwell
Procedural wells and shop offers vary runs
Nyan Cat: Lost In Space
Procedural obstacle layouts add some unpredictability
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
Nyan Cat: Lost In Space
Upgrade choices and route knowledge improve runs
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.
