This was a much better experience than I expected. Rather unbelievable!

Side-effect of the data: clearly the model is better than I normally am at playing, as it spontaneously did several things I had not told it to do and wouldn't really know how to do (at least not with a keyboard).

Really remarkable, congrats!

It feels like playing on a very slow computer. Except that sometimes it just randomly decides you pressed the flip button. Really impressive.
