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.

Execution · Practiced Mastery
Roguelite blending twin-stick shooting with tower-defense crystal escorts.

Optimization · Practiced Mastery
Progressing through a contaminated open world by solving its scenario tech tree and optimising base builds.
Endless Dungeon leans Execution (Practiced Mastery); Once Human leans Optimization (Practiced Mastery).
Endless Dungeon leans a little harder on execution, though the gap is small.
Endless Dungeon
Twin-stick shooting during wave defenses
Once Human
Third-person shooting and dodge rolls require real aim and timing
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Endless Dungeon
Monster waves follow spawn rules, not adaptation
Once Human
Deviant creatures follow scripted attack patterns only
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Endless Dungeon
Procedural floors and random resource rooms
Once Human
Deviant spawn composition and loot tables carry meaningful randomness
Once Human leans a little harder on optimization, though the gap is small.
Endless Dungeon
Turret placement and route economy planning
Once Human
Scenario tech tree, base construction, and gear crafting are solvable
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.
