Update: Light Energy

Release Notes

HealthBar
A health bar has been added to display the character's health and their light energy. The player also has a weak health regeneration of 10% every 5 seconds.
Pieces of light
That drop from enemies have been added and they replenish the light energy when at full health. Pieces of light also drop from the player upon receiving damage.
Light Saber attack
The light attack is capable of dealing devastating damage, especially effective against groups when the light energy gauge is at least halfway full.
