/*

Spell 3 (Sakuya):

Remilia moves to the horizontal middle and starts slowly moving from top to bottom, firing slow red rings. As she moves, she fires bursts of knives to the sides that reflect off the walls towards the player (one burst per 3 rings).
When she reaches the bottom, she fires a large burst of knives everywhere, following the same reflecting formula.

Parameters:

- Movement speed (in frames)
- Ring density
- Ring speed

- Density of one knife line
- Speed of knives

- Number of knife rings
- Density of each knife ring
- Speed of each knife ring
