I see where you're coming from, right now I think the enemies are easy enough that if they were more obvious visually it could make the game too simple. I'd like to add more enemies with more advanced behaviour (sniper, flying bots, assasins, stuff like that) which would add a layer of difficulty, thus allowing their overall visibility to increase as it wouldnt be detrimental to the gameplay! Thanks for bringing it up though! And thank you for playing :)
