head to head
Neither is simply harder - they are hard in different places. Morphblade demands more variance; Portal demands more execution.

Optimization · Pure Optimization
A turn-based tactics puzzle about chaining weapon transforms against bug waves.

Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Morphblade leans Optimization (Pure Optimization); Portal leans Optimization (Pure Optimization).
Portal leans clearly harder on execution.
Morphblade
Turn-based movement removes any twitch demand
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.
Morphblade
Bugs follow scripted behaviour, not modelling you
Portal
No adversary modeling player.
Morphblade leans clearly harder on variance.
Morphblade
Enemy spawn waves have randomised composition
Portal
Deterministic chambers; no randomness.
Morphblade leans a little harder on optimization, though the gap is small.
Morphblade
Planning movement to chain weapon transforms optimally is the puzzle
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.
