head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Tests physics contraption engineering against fixed puzzle levels.

Optimization · Pure Optimization
Noir stealth puzzler about rewiring buildings so guards defeat themselves.
Bad Piggies leans Optimization (Pure Optimization); Gunpoint 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.
Bad Piggies
Light steering of contraptions after building
Gunpoint
Jump timing matters occasionally, lightly
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Bad Piggies
No opponent of any kind
Gunpoint
Guards patrol on fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bad Piggies
Levels are fixed and repeatable
Gunpoint
Levels fully visible and deterministic
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bad Piggies
Contraption engineering for three-star solutions is the game
Gunpoint
Crosslink rewiring puzzles have clean optimal solutions
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.
