 Since 0.9.21: A value of 0 indicates that each flake should keep displaying the exact frame that was selected randomly when the flake was created.
 *Tip*: If you want to have multiple static flakes in 0.9.20 or earlier, you can set the animation length to a ridiculous high value. Sometimes, a flake will still change the displayed frame, but it will rarely happen.
  * `speed`: Rotation speed of flake
- * `fall speed`: Falling speed of flake
+ * `fall speed`: Falling speed of flake. Since 0.9.23, this can be negative for rising flakes
