I'm getting the same call stack size error. Looks like it happens right when the first guy gets all the way cured. The moment he turns all the way white - call stack error.
I wish there was something on the background as a reference to motion, I can't really tell if I'm moving and in what direction sometimes.
Thank you, UnitVector, and Ryuzaki for pointing out the error. There was an infinite loop hidden in my code that I didn't catch before! I've fixed it and will be uploading a new version without the error soon. I'm also adding a very basic grid to help with motion reference.
Thanks for the suggestions and thanks for playing!
