im on 5. This doesnt help if you colour blind!! Sorry 'bout that. I didn't quite think about color blinds when I made the game. :( Nice to see that my game has become so popular. :) I personally don't like cheating in this kind of games and I hope that you wouldn't either. Little hints are OK, but ...
