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 melancholy mobile rhythm game built around piano pieces and a wordless fairy tale.

Execution · Pure Mechanics
A hand-animated revival of Rayman's 2D platforming.
Deemo leans Execution (Pure Mechanics); Rayman Origins 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.
Deemo
Piano-style falling notes need clean two-thumb accuracy
Rayman Origins
Fluid run-jump-glide chains
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deemo
Charts are fixed
Rayman Origins
Scripted enemies
Rayman Origins leans a little harder on variance, though the gap is small.
Deemo
No randomness
Rayman Origins
Deterministic levels
Rayman Origins leans a little harder on optimization, though the gap is small.
Deemo
Memorizing dense piano passages
Rayman Origins
Lum routing for perfection
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.
