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

Optimization · Pure Optimization
A musical adventure where learning and reversing melodic spells forms a closed combinatorial puzzle system.

Optimization · Pure Optimization
A Tetris-meets-Lemmings puzzler testing deterministic block-placement planning.
Loom leans Optimization (Pure Optimization); MouseCraft leans Optimization (Pure Optimization).
Loom leans a little harder on execution, though the gap is small.
Loom
Musical spell sequences require accurate note input under light pressure
MouseCraft
Placing tetrominoes calmly - mild timing on live mice
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Loom
Fantasy narrative with scripted antagonists
MouseCraft
Mice march predictably like Lemmings
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Loom
Deterministic world with no randomised elements
MouseCraft
Levels are fixed and fully visible
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Loom
Learning and combining distaff spells in the correct order is a fully solvable logic system
MouseCraft
Each stage is a deterministic block-placement puzzle to solve
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.
