add damage animations

[flip40]

not sure if literal animation in unity, however the common cliche is to have a player flicker and be invulnerable for a few seconds after taking damage, and an enemy to perhaps flash red or something to indicate being hit.

Depending on the mechanics and style of the game, may want the player to not flicker and be invulnerable for a bit after taking damage, instead the player would continuously receive damage until they are either dead or not receiving damage anymore.

Invincibility frames seem to lead to interesting things though
