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

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

Execution · Pure Mechanics
A brutally precise platformer about dying thousands of times.
Celeste leans Execution (Pure Mechanics); Super Meat Boy 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.
Celeste
Pixel-perfect dashes and wavedashes are the entire skill.
Super Meat Boy
Pure twitch platforming, frame-perfect jumps
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.
Super Meat Boy
No adaptive opponent
Super Meat Boy leans a little harder on variance, though the gap is small.
Celeste
Zero randomness; every screen is deterministic.
Super Meat Boy
Fully deterministic levels
Celeste leans a little harder on optimization, though the gap is small.
Celeste
Route choice and tech selection are learnable but light.
Super Meat Boy
Route memorization optimizes times
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.
