The game is well optimized, to the point where you can literally open it on a cell phone (yes, I did that test).
I had no problems with the antivirus, but when used in Wine, the game has a problem initializing the character creator, but I believe it is just a big problem with this build, so, For an alpha, everything is going very well, I hope to be able to test the next versions, I'm loving it.
(Tested on Windows, Linux(Wine), Android(Wine))
