Ok, so this might be a silly app to invert but my wife plays it all the time so I installed it and it's kinda fun but it needed some doctoring up..
.. I think there's a paid version but this is just the free one.. it installs like a normal app but you'll need to uninstall your old one first, then install mine.. on the stock app the text colors all over were secondary system text colors but I am 99% sure I got all of them to point to either #ffffff or primary (which is usually white on stock roms) but let me know if ya find any black on black.. and as you can see, I suck at this game.. lol.. Enjoy!
