I rebuilt the game tonight using Unity 5, so there may be some graphical improvements with the game. I also brought the Windows desktop build up to the same version as the web version.
I noticed a small bug where you can catch a sheep twice, which may cause an error but does not appear to crash the game. I will try to fix this when I have the time, but honestly the game just needs to be rewritten. This was the first game that I developed in Unity over two years ago, and I’ve gotten much better with Unity since that time.
