The new clue will be phrased like that 'AS IF I WOULD SHARE MY CODE TO ANYBODY AHAH' Remember what the smalley in level -1 was saying ? Take it together with what the smalley is saying
Also there is an additionnal clue in level 5/-2 hidden somewhere
OH MY GOD ITS THAT CODE ISNT IT
and now Im stuck on the final level
I've initially tried the "I AM SHY" code as it was also seemed related...
