head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
Zero-gravity physics game about wrestling floppy cosmonaut limbs through space-station chores.

Execution · Pure Mechanics
A hand-animated revival of Rayman's 2D platforming.
Heavenly Bodies 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.
Heavenly Bodies
Deliberately awkward limb-by-limb zero-g control
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.
Heavenly Bodies
No opposition
Rayman Origins
Scripted enemies
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Heavenly Bodies
Fixed scenario layouts
Rayman Origins
Deterministic levels
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Heavenly Bodies
Task order and clever anchor points
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.
