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 2D sandbox where preparation and gear tiering carry boss fights.

Optimization · Pure Optimization
A grid dungeon crawler testing build choices, puzzle-solving and enemy-type counterplay.
Terraria leans Optimization (Pure Optimization); Vaporum leans Optimization (Pure Optimization).
Terraria leans a little harder on execution, though the gap is small.
Terraria
Boss fights require dodging and aim under pressure.
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.
Terraria
Bosses use scripted attacks; no adaptation.
Vaporum
Enemies follow fixed behaviours per type
Terraria leans a little harder on variance, though the gap is small.
Terraria
World seeds and loot drops randomized.
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.
Terraria
Gear progression and arena prep solve every boss.
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.
