Massive shoutout - she delivers bangers every. damn. year 🔥

Guess I owe you more tails talk! 🐾
Cat tail is implemented as Verlet rope with inverted gravity.
Mouse tails follow the logic from Emanuele Feronato's awesome “String Avoider” tutorial series - I finally found a way to sneak that into a game!

Initially, due to the round head-collider under gravity, the cat’s body stretched into an egg-like oval. To squash it flatter, more bun-like, I fake-support the butt with an invisible floor 👀

When the cat's head moves too fast, it can slip out of the body 👀
I make the body catch up by adding overshoot to all soft-body vertices. Verlet integration shines here - momentum stays, as I also adjust the previous positions of the body points 🤓

The cat is controlled by a circular collider inside a soft-body shell.
In fact, all collisions with the ground and field bounds are calculated as collisions with a simple circle 🎓
