LOVE IT! And love the gamepad support, will write more when I finish the demo :)
Oxygen is there for that very reason but with that being said, it's still really in the testing phase on how much it should drain and where it should be used, etc.
So things will likely change over time, hopefully for the better, what I can say though is that it will only be used in specific areas and not everywhere.
Thanks for the feedback. :)
