When I first played the beta of Fearless Brain I managed to get a score of about 8 and getting higher seemed impossible. I sincerely thought 24 balls should be enough for everyone since nobody would make it.
Then after training regularly I got my scores higher and even managed once at five in the morning to do a full loop (under the nickname "Mémoire de Poule"). To me this was like a miracle and I guess I was just lucky.
Now I see some people have managed to go through several loops, including one guy from Taiwan who is now topping the charts with an amazing four loops. I am truly impressed.
Maybe I'll release a new version that allows for an unlimited number of balls just to see how far some people will be able to go :-)
