i think it just hard game...but it's not hardest game yet. Beacuse if we do it more seriously we can do it well..
i could be wrong, but once i got to the 3rd level it feels different from version 1. i don't remember having to "unlock" anything. anyway, it was still fun and it feels a little more fast pace than version 1 also, but it also could be 'cause i haven't played it in a while.
If u will do it more than one time u can do it easily so it is not hardest game just a puzzle game ///////////////////////////////////////////////////////////
Difficult or not is not important. Important that we played through it. But it is not as important as it is fun or not. ู^___^
