How do I keep the Heart value and the Bone value from depleting? Suddenly, all of the items that I am able to give the Morphling stop affecting the Heart/Bone values once I evolve the Morphling to the 'Urchin' stage, and it's very tedious to get back to that stage; I cannot learn anything through the suggested avenue of trial-and-error when an error is so punishing that I have to restart from the beginning.
Do I need to vary the Food/Materials/Interactive Items that I give it? But then that prevents me from being able to focus on any evolutionary path! I apologize if I sound excitable/angry, but I simply wanted to unwind for a short time and here I am being bested by a point-and-click game.
