PortalvsTiny Brains
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Portal
Optimization · Pure Optimization
The portal-gun puzzle game whose solutions are everything.
Tiny Brains
Optimization · Pure Optimization
Co-op physics puzzles solved by combining four characters' distinct powers.
Portal leans Optimization (Pure Optimization); Tiny Brains leans Optimization (Pure Optimization).
PortalTiny Brains
Axis by axis
Execution4 vs 3
Portal leans a little harder on execution, though the gap is small.
Portal
Portal placement timing modest.
Tiny Brains
Light physics handling, occasionally timed sections
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.
Tiny Brains
No adversary - the puzzle is the opponent
Variance0 vs 1
Tiny Brains leans a little harder on variance, though the gap is small.
Portal
Deterministic chambers; no randomness.
Tiny Brains
Puzzle rooms are fixed once seen
Optimization8 vs 7
Portal leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
Tiny Brains
Combining four powers into solutions is the whole test
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.
