Hi, it can be used as an enemy in a game maybe add some features like follow. The fade effect is nice. Put some food which they eat.
//step event of obj_worm_sibling
if place_meeting(x,y,obj_food){
spd +=1
timerGoo -=0.1
}
//step event of obj_food
if place_meeting(x,y,obj_worm_sibling){
instance_destroy()
}
