Hi! Thank you so much!!! :D It mostly depends on where are you working with them! If it's in Unity (or mostly any other game engine), then you should be able to just add the characters.blend sheet to the scene and then click the individual ones so you can pop them out of their parent obiect!
ps. I was planning on updating the pack in a couple of days! What features would you like to see!! :O I was planning to add some farm animals!
