I definitely understand that. Bit late on my part, but with bubble kitty the key lines in Ellie's spinning and jumping. I've also found it easier to do on the ground so one can jump to avoid a certain attack.
With Fire kitty, it's largely about keeping moving and grabbing logs when safe to do.

They can definitely hurt, that's for sure. Which ones are giving you grief and how?

Sierra. A kind yet gullible woman with a great desire to be helpful to other people. Often tricked into being a test subject for Alyx's experiments, yet never learns. Possesses a libido that frightens even her friends.

Alyx, a scientific minded man who while brilliant, often puts more effort into satisfying his own selfish desires. Kept from going full "mad scientist" by Dia's watchful eye. The one responsible for Ruby's condition.

Dia, a short woman with a great interest in making people taller than her smaller. Heiress to a wealthy family business, she funds Alyx's experiments in the hopes of acquiring new toys.

Usually down for sexy size shenanigans, she tends to get flustered and panicky when control is taken away from her, but she doesn't necessarily hate the idea of being treated like a toy no matter how much she might protest.
