This is a shader issue, and I'm not sure how to fix it. You could try updating your graphics drivers or playing the game on a different device. In a Windows 10, 64 bit desktop build it's most likely going to be an incompatibility with your video card or graphics driver version. (Win10 64 bit is generally our most stable & compatible build!)
You may also have some luck running the WebGL build in a web browser or downloading it to play locally. Unfortunately WebGL is a little sluggish and doesn't have save support.
Good luck! Sorry you're having issues! :O
