I've been wondering this. Not looking for it to be perfect as I tried Vulpes single stat mag guide and my mag glitched it's evolution into a different one.
So, I'm using the tetheala client made by Sodaboy to attempt to play the game offline and everything started going as planned until I tried to change my resolution. There is no option in the drop down menu for a resolution. I've tried:
-re-downloading client
-turning off anti-virus softwares...
