+How it works?
+All heart containers are instantiated at start, and unused heart containers are disabled until being used.
+The property fillAMount of UI Images are used to fill the hearts. 1 heart equals to 1 health.
+
+Why using floats?
+Well, this assets was originally part of a game of mine, where the player would have a health between 3 and 20. Monsters
+would deal about 1 damage, and later in the game the player could get armors (reducing damage by 25% or 50%, multiplying
+the damage by 0.75f or 0.5f, respectively).
