Finished the first level and loved the game, and it ran fine until the most recent update, and now the screen is a green and black amalgamation of colors. Not sure if this is a common problem or not.
I'm playing on a Windows computer, it's had problems before, but generally only with running speed. It's not even close to a perfect one, so chances are it's just an issue with a virus of some sort that's been on here for a while. Sorry for the bad quality, I couldn't take a screen capture so I had to take a picture and raise the brightness.
