head to head
Portal asks more than Chaos on Deponia, and the gap is execution.

Optimization · Pure Optimization
The second Deponia chapter continues elaborate fixed-solution puzzle chains demanding methodical thinking.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Chaos on Deponia leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Portal leans clearly harder on execution.
Chaos on Deponia
Same interface as original; zero reflex component
Portal
Portal placement timing modest.
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Chaos on Deponia
Continuation of scripted comedy narrative
Portal
No adversary modeling player.
Chaos on Deponia leans a little harder on variance, though the gap is small.
Chaos on Deponia
Deterministic solutions throughout second chapter
Portal
Deterministic chambers; no randomness.
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Chaos on Deponia
Increasingly complex puzzle architecture rewards systematic inventory management
Portal
Pure puzzle-solving optimization.
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.
