  * `number`: Number of visible flakes.
  * `frames`: Number of frames used in `Flake.png`
  * `frame ticks`: Number of ticks a frame is shown, after that the next frame is shown (a tick currently equals 1 millisecond). A value of 0 indicates that each flake should keep displaying the exact frame that was selected randomly when the flake was created.
- * `speed`: Rotation speed of flake
- * `fall speed`: Falling speed of flake. This can also be negative for rising flakes

+ * `vertical speed`: Vertical speed of flake. Positive values are for falling flakes, while negative values make them rise
