Thanks! Morphology does affect both movement and metabolism, but by design it’s modeled as biological abstraction rather than full physics.

Traits like spikes, tentacles, lobes, adhesion, and size add drag/weight, so complex or armored bodies are slower and less agile. Bigger bodies and complex structures also have higher metabolic upkeep. It’s not true fluid dynamics or area/volume math, but it’s tuned to produce the same evolutionary tradeoffs.

So you get: big and complex = strong but slow and hungry. Small and simple = fast and cheap but fragile.
