Today was kind of a slow day: I had many things to do, so development was kind of light...

Nevertheless, I've still managed to do something...

I've added a way to highlight items through emission (not unlike how we did it previously) and make enemies blink when they get hurt.

It wasn't really hard: because this is Unity, the surface shader got us covered. It was just one simple line of code. 

#ifdef IS_EMISSIVE
o.Emission =  lerp(fixed3(0, 0, 0), _EmissionColor.rgb, _EmissionRatio);
#endif
