For release 0.1.0 that's correct. Not for next release though.
Alright, so when the next release comes out, I read you are adding an ON-OFF switch. I am guessing that's what you meant? XD
Also, Random request, Could you add an opacity meter? Is it possible? Some stuff I need to read is covered by the overlay and I can't see it. At random points in the game, there is text on the top left of the screen.
GREAT Job by the way! REALLY awesome overlay ;] and I don't feel like I am cheating by doing this xD
