It really messed up my research with DQN RL variations, because it is possible to bypass pipe over the screen.

See screenshot: http://www.evernote.com/l/AClrdjOMAFBLSLm1-ZvYqa-63AOtriZ9NoI/ This state gives reward = 1.0 (notice bird partially over pipe)

player height 24, but it is enough to be at position -20 to bypass pipe.

Can you please give me rights to push patch to repo? I am planning to work with your repo and I could find more bugs.
