Fiendish Swarm (Active - 2 Room)

On use, lose all HP down to 1 full heart. All health lost in this way becomes Heart Orbital Flies. At the end of the room, all the Heart Orbital Flies gained turn back into the player's health.

The AlGoRiThM:

• If the player has 1 or more Heart Containers and 1/2 or more Red Hearts, bring them down to half a Red Heart and remove all other heart types.
• If the player has no Red Hearts and 1/2 or more Soul Hearts, bring them down to half a Soul Heart and remove all other Heart Types. Empty Heart Containers and Bone Hearts do not matter. If a Bone Heart is in the first position, remove it anyway.
• If the player has no Heart Containers and no Soul Hearts (i.e. only Bone Hearts), bring them down to 1 Bone Heart.
• Black Hearts count as Soul Hearts for all above conditions.
• Rotten Hearts count as Red Hearts for all above conditions. If a player only has Rotten Hearts with no Red Hearts, we'll bring them down to 1/2 Red Heart anyway.
