PortalvsShadwen
Shadwen asks more than Portal, and the gap is variance.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Shadwen
Optimization · Pure Optimization
Using time-rewind to pre-solve grapple and kill sequences against fully deterministic guard patrols.
Portal leans Optimization (Pure Optimization); Shadwen leans Optimization (Pure Optimization).

Axis by axis
Execution4 vs 3
Portal leans a little harder on execution, though the gap is small.
Portal
Portal placement timing modest.
Shadwen
Grapple hook timing and kill windows need care but are forgiving
Reads0 vs 1
Shadwen leans a little harder on reads, though the gap is small.
Portal
No adversary modeling player.
Shadwen
Guards follow scripted patrol arcs without profiling player tactics
Variance0 vs 2
Shadwen leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
Shadwen
Child NPC pathfinding adds minor unpredictability to routing plans
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Portal
Pure puzzle-solving optimization.
Shadwen
Time-rewind and rope construction enable full pre-optimisation of every kill sequence
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.
