head to head
Aragami asks more than Portal, and the gap is variance.

Optimization · Pure Optimization
Managing shadow essence resources to chain teleport eliminations through deterministic guard patrols.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Aragami leans Optimization (Pure Optimization); Portal 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.
Aragami
Shadow leap timing and kill animations need clean inputs
Portal
Portal placement timing modest.
Aragami leans a little harder on reads, though the gap is small.
Aragami
Aragami guards patrol fixed routes without player-specific adaptation
Portal
No adversary modeling player.
Aragami leans clearly harder on variance.
Aragami
Scroll placements are consistent; very little hidden randomness
Portal
Deterministic chambers; no randomness.
Portal leans a little harder on optimization, though the gap is small.
Aragami
Shadow essence management and teleport sequencing define approach efficiency
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.
