head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, 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
A chaotic comedy adventure whose elaborate multi-step puzzles test patience with absurd causal chains.
Armadillo Run leans Optimization (Pure Optimization); Deponia leans Optimization (Pure Optimization).
Armadillo Run leans a little harder on execution, though the gap is small.
Armadillo Run
Building structures has no twitch requirement
Deponia
Point-and-click with no timing elements
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
Deponia
Comedy adventure with scripted characters throughout
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Armadillo Run
Physics is deterministic once a structure is built
Deponia
Deterministic puzzle world with fixed solutions
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
Deponia
Convoluted Rube Goldberg puzzle chains demand careful causal mapping
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.
