There is no character level system in this game with attribute points to increase by pressing an up arrow or a (+). There are no concrete skills to upgrade. Everything is based on custom skill creation and muscle use. However, there are DNA Points.
Your character will progress in the game based on its actions, based on your actions. Its body is made up of several muscles and the ability to control those muscles effectively. You have an unlimited number of skills, and you must learn to use each one by learning to use each muscle. How well your character executes each skill is based on the average ability to control muscle groups used in the skill.
You are a coreographer. Just like in other MMOG's you click a button or move the mouse or press a key and your character does something. There will be a large number of preset skills available to those who don't want to make their own, but the skill creation system is the grand feature of the game itself. Making a skill is kind of like making a 3D animation in a very good 3D program. Simply drag body parts around the right way, or give them a destination point or angle.
Your character will not gain levels. Instead, your character will gain muscle tone or become more agile. Your character may become faster or lighter on its feet. It may become able to communicate better or be able to interpret and notice things more. All of the above is possible.
