Update 1.0

Changed:

enemy moving logic (doesn't changes gameplay for now)

Added:

health system - now you can see how much health you have

knockback system - not only you can obtain melee damage! If enemy catches you, Armored Sigma will automaticaly strike back, knocking enemy back, delivering damage and stunning him for few seconds. However, you also take damage from that combat.

Beta shotgun firing logic - did you ever saw a machine gun firing pellets like shotgun and reload like pump action? No, because everyone makes new weapons for new mechanics. 

To use shotgun mode click D on start screen, to switch back to LMG press M.

Blood - now you can see blood splashes on enemies when you hit them with bullets (or pellets)

Penetration system - for now it doesn't affects gameplay because all projectiles have penetration to kill only 1 enemy, but in future will be added more bullet types
