It's so haaaard!!!
I remember asking you to do a version where each sequence would just continue the previous one, the intention beingto flex the memory muscle. I remember you kindly gave it a try and we agreed it wasn't that satisfying. Playing the game again after some time, I still think that "muscle memory" muscle could be teased with random sequences of predefined patterns. Like chains of classical Street Fighter moves or the Konami cheat code pattern. If that makes sense.
Great entry!!!
