Instead of placing packages manually, created script for that. It spawns package and customer pair with the same color (package sprite is Square and customer is Circle). Logic checks that the package was delivered to correct customer. The script has list of spawn points and spawns the number of pairs to all available points on Awake as well as spawns one more pair on package delivery. Spawn points are randomly selected from the list.
