The idea of the app is to allow you to customize your units in a way that can give you more freedom of strategy in battle. This is possible by allowing you to design your own units, which gives you more control over their strengths and weaknesses.

Each unit is made up of several parts, such as the body, the head, the eyes, the ears, etc. Each part has a certain amount of health and energy, and if you damage or kill a part, you will lose the corresponding amount of health and energy. If your energy is completely drained, you will die.
