head to head
Ghostrunner asks more than Celeste, and the gap is optimization.

Execution · Pure Mechanics
A deterministic precision platformer about executing pixel-perfect dash routes.

Execution · Pure Mechanics
A first-person cyberpunk slasher where everything dies in one hit, including you.
Celeste leans Execution (Pure Mechanics); Ghostrunner leans Execution (Pure Mechanics).
Celeste leans a little harder on execution, though the gap is small.
Celeste
Pixel-perfect dashes and wavedashes are the entire skill.
Ghostrunner
One-hit-death parkour and slashing demand near-perfect inputs
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Celeste
No opponent; level hazards are fully scripted.
Ghostrunner
Enemy placements are fixed
Ghostrunner leans a little harder on variance, though the gap is small.
Celeste
Zero randomness; every screen is deterministic.
Ghostrunner
Deterministic levels
Ghostrunner leans clearly harder on optimization.
Celeste
Route choice and tech selection are learnable but light.
Ghostrunner
Route planning and enemy-order solutions define fast clears
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.
