hi guys, thanks for comments!
@Galeon: sure, i was thinking about being able to drop bombs because blueprint-wise it’s easy to modify the existing projectile
hey @Pampers: the other blue helicopters are on player’s side while the enemy crafts are grayish. i hope they are distinct enough in colors/shape… i do want to improve enemy colors tho but i want to avoid the obvious red choice : )) buildings are very temp still, player’s HQ ( or police station ) should be less blue and very distinct since its destruction is often enemy objective.
@OldAccount29 : you’re right and thanks for taking the time! the thing with explosion colors that bugs me is that there is no gradient from center-out. right now they start white and cool evenly. i’ll try fixing it with a simple fresnel when i find the time. the smoke lingering is easily adjusted but i need to keep in mind the performance because there is lot of things exploding all the time 
cheers!
