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
Monochrome adventure lived in sixty-second loops that reward ruthless route planning.

Optimization · Pure Optimization
A grid dungeon crawler testing build choices, puzzle-solving and enemy-type counterplay.
Minit leans Optimization (Pure Optimization); Vaporum 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.
Minit
Simple combat and movement
Vaporum
Real-time grid-dancing around enemies needs some timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Minit
World is fully scripted
Vaporum
Enemies follow fixed behaviours per type
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Minit
Secrets are hidden until first discovery
Vaporum
Dungeon is authored; loot mostly placed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Minit
Routing tasks into sixty-second lives is the core test
Vaporum
Gear loadouts, rig builds and puzzle solutions are the core
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.
