In terms of game balance, do you think I should use mana? I was thinking of using more of a threshold system, where when you use magic, it contaminates you with magical energy, which goes away slowly over time. While contaminated, spells you cast have a slightly greater chance of being miscast, and you may have random magical effects appear in your vicinity, including mutations.
Also I thought of a way to somewhat balance will control over materials. You can use telekinesis on any material you have will control over, but the power of said TK will be rather low. You can make a material turn into any inanimate shape, and if it's living you can turn it into one of the structures that it would naturally form. So flesh can make muscles and other organs, fungus can make sporepods, mycelium, and mushrooms, plants can make leaves, and anything can make a sword, though only some things will make good swords. This means that if you want to make an animate construct, you need to use flesh for muscles. You could then change the material into something else, and it would still function, but in order to make the muscles in the first place, you must use flesh. For composite materials, they can be controlled if you have control over any of the materials that make them up, but you will suffer a % penalty if you don't have control over all the materials that make them up. For example, if you have control over 1 out of 2 materials in a composite material, you suffer a 50% penalty, 1 out of 3 you suffer a 66% penalty, etc.
