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
Macabre management sim about running a medieval cemetery as a business.

Optimization · Pure Optimization
A Tetris-meets-Lemmings puzzler testing deterministic block-placement planning.
Graveyard Keeper leans Optimization (Pure Optimization); MouseCraft 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.
Graveyard Keeper
Light action farming inputs
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.
Graveyard Keeper
Villagers run on fixed schedules
MouseCraft
Mice march predictably like Lemmings
Graveyard Keeper leans a little harder on variance, though the gap is small.
Graveyard Keeper
Minor drop randomness
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.
Graveyard Keeper
Sprawling tech trees and grind-route efficiency
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.
