Aside from mechanics, you could simply add cosmetic touches—like a more hunched walking animation when it’s raining, or her flinching at a thunderclap. You could also include idle animations where Sabia shivers because she’s gotten wet.
Great devlog! Progress is going by leaps and bounds.
Considering how development of other Exhibit games is going, all hope lies with you. Great devlog, I'm looking forward to it.
