Axis by axis
Execution3 vs 4
Portal leans a little harder on execution, though the gap is small.
Deathtrap
Some real-time aiming in tower placement and hero control.
Portal
Portal placement timing modest.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Deathtrap
Enemy waves are scripted or randomized, not adaptive.
Portal
No adversary modeling player.
Variance4 vs 0
Deathtrap leans clearly harder on variance.
Deathtrap
Wave composition and loot rolls add unpredictability.
Portal
Deterministic chambers; no randomness.
Optimization8 vs 8
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Deathtrap
Tower and build optimization is the deeply solvable core.
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.
