A lot of games are getting signaled as malware. It is not developer's fault and Kongregate is working on it. You can check progress here http://www.kongregate.com/forums/7/topics/735846. I think it should mostly be solved anyway (i can access the game and so other people)
Codes are the drawback to this puzzle, would help to have some sort of log/journal as to what codes go together, and help eliminate backtracking and writing it all down.
