head to head
Mindustry asks more than World of Goo, and the gap is optimization.

Optimization · Pure Optimization
Factory-meets-tower-defense; belts feed your defenses.

Optimization · Pure Optimization
A physics puzzle game about building wobbly towers and bridges from living goo balls.
Mindustry leans Optimization (Pure Optimization); World of Goo 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.
Mindustry
some tower placement under pressure
World of Goo
Placing goo balls needs only mild precision
Mindustry leans a little harder on reads, though the gap is small.
Mindustry
scripted enemy waves
World of Goo
No opponent exists
Mindustry leans a little harder on variance, though the gap is small.
Mindustry
map layout variation
World of Goo
Physics are visible and deterministic
Mindustry leans clearly harder on optimization.
Mindustry
factory belts and logistics chains
World of Goo
Tower structure and goo economy are solvable per level
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.
