head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is variance, and it is a single point.

Optimization · Pure Optimization
A minimalist puzzle platformer about deducing box-chain solutions.

Optimization · Pure Optimization
A musical adventure where learning and reversing melodic spells forms a closed combinatorial puzzle system.
BoxBoxBoy! leans Optimization (Pure Optimization); Loom 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.
BoxBoxBoy!
Box creation and movement need no precision
Loom
Musical spell sequences require accurate note input under light pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
BoxBoxBoy!
Solo puzzle game with no opponent
Loom
Fantasy narrative with scripted antagonists
Loom leans a little harder on variance, though the gap is small.
BoxBoxBoy!
Puzzles fully deterministic, nothing random
Loom
Deterministic world with no randomised elements
BoxBoxBoy! leans a little harder on optimization, though the gap is small.
BoxBoxBoy!
Deducing box-chain shapes to clear obstacles is the game
Loom
Learning and combining distaff spells in the correct order is a fully solvable logic system
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.
