I have another question: can you make the shield protect missile impact and concussion rifle projectiles? Something like that would be good because many times the Force is not enough to protect you from these projectiles.
Sorry for the very late reply. I don't check deviantart too often.
I just tried to log in to where it was uploaded, but the system was down. I'll try to log in again tomorrow and get you the link (pun not intended.)
The shield is always raised. There is no way to tie it to the right mouse button. So the shield will be there for defense as long as you don't attack. This is also similar to how it was in Twilight Princess.
