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 first-person runner testing reflexive timing at extreme speed.

Execution · Pure Mechanics
Arcade run-and-gun reflexes against fully memorisable boss patterns.
Fotonica leans Execution (Pure Mechanics); Sunset Riders leans Execution (Pure Mechanics).
Fotonica leans a little harder on execution, though the gap is small.
Fotonica
One-button timing at extreme speed defines everything
Sunset Riders
Dodging bullet spreads and snap-shooting bosses is everything
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Fotonica
Solo runner, no opponent to predict
Sunset Riders
Bandits and bosses cycle memorisable arcade patterns
Fotonica leans a little harder on variance, though the gap is small.
Fotonica
Tracks are fixed once learned, little randomness
Sunset Riders
Spawns are deterministic each credit
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fotonica
Memorizing track geometry plans optimal lines
Sunset Riders
Pattern memorisation for one-credit clears is the meta-game
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.
