I definitely don't want to make you do any work, but if you keep having problems i'm happy to debug your setup with you (just email eieiogames@gmail.com) for as long as you have patience!
in my experience the face detection is relatively good but the eye detection is still a little spotty / could be tweaked[1]. Although within reason that's just part of the fun.
I wonder if I print a set of open eyes and test your game.... Will it detect the trick? Would I win or get banned?
Jokes aside, eager to test ; )
