The portal-gun puzzle game whose solutions are everything.
Vaporum
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.
Vaporum
Real-time grid-dancing around enemies needs some timing
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal
No adversary modeling player.
Vaporum
Enemies follow fixed behaviours per type
Variance0 vs 2
Vaporum leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
Vaporum
Dungeon is authored; loot mostly placed
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.
Vaporum
Gear loadouts, rig builds and puzzle solutions are the core
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.
