We probably won’t have any controls for player illumination as I think our options screen is already getting excessive. The best solution may be for us to just try toning it down a bit. Either way, I think it is not something you really notice at all when playing.
The green bar represents energy (or mana) that is used to perform skills / cast spells. We decided to tint it greenish to match the color of aetherial energy in the game.
