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 tower defense game built on optimal placement and build strategy.

Optimization · Pure Optimization
Designing and optimizing a theme park's layout, pricing, and guest flow to maximize satisfaction and profit.
Kingdom Rush 5: Alliance leans Optimization (Pure Optimization); Planet Coaster leans Optimization (Pure Optimization).
Planet Coaster leans a little harder on execution, though the gap is small.
Kingdom Rush 5: Alliance
minor click-timing for abilities
Planet Coaster
Precise track and scenery placement rewards manual dexterity
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kingdom Rush 5: Alliance
fixed enemy waves, no adaptation
Planet Coaster
No adaptive opponent; guests follow scripted happiness rules
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kingdom Rush 5: Alliance
minor spawn/damage randomness
Planet Coaster
Guest mood noise is low and quickly mappable
Kingdom Rush 5: Alliance leans a little harder on optimization, though the gap is small.
Kingdom Rush 5: Alliance
tower placement, build optimization
Planet Coaster
Queue routing, pricing, and ride placement are the solvable core
