it doesn't always allow you to but if you press the cancel button when shown the offspring it will ask you if you want to release themI don't like that I'm forced to keep every offspring produced, especially when the ascension thing is so far from the pen and closes the menu every time I use it for one critter. When did it get changed so that you don't have a "release into the wild" option? I feel like developers are getting dumber or something as time progresses in my life.
