The analog stick is an auto dash, even when the setting is turned off. Also, the "double tap" window is way too long. When I'm trying to turn around, she'll start to sprint, and I'll fall off an edge because I wasn't expecting the sudden sprint.
With a lot of platformers. They usually have a "Sliding" state. For Instance, say she's dashing and the player turns the opposite direction. With others, they would have a very short "sliding" animation where it slows you down but after like 1/3 of a second, she's back at full speed the other direction. It's easier for the player to adjust and compensate. Only for dashing tho.
