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.

Optimization · Pure Optimization
A physics construction puzzler about building cost-efficient structures to guide an armadillo.

Optimization · Pure Optimization
Atmospheric sci-fi puzzler about swapping consciousness between your own clones.
Armadillo Run leans Optimization (Pure Optimization); The Swapper leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Armadillo Run
Building structures has no twitch requirement
The Swapper
Light platforming; precision rarely gates progress
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Armadillo Run
No opponent; pure physics sandbox
The Swapper
No opponent exists
Armadillo Run leans a little harder on variance, though the gap is small.
Armadillo Run
Physics is deterministic once a structure is built
The Swapper
Deterministic rooms with no hidden state
Armadillo Run leans a little harder on optimization, though the gap is small.
Armadillo Run
Designing efficient physics structures within budget is the whole game
The Swapper
Clone-placement puzzles have fixed solvable solutions
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.
