It is a possibility I may have left out this signpost by accident without realizing it. With over 50 to collect, this is an easy thing to over look. I will be looking over the issue and patching the game to 1.01 which will include the fix to the signpost. Since you have bought the guide, collecting all the signposts unlocks the center chest which contains the same info as in the guide to unlock the hidden class. Please refer this to unlock the class. This key item is NOT required to gain access to the character, and she may be used in a New Game as well as long as you know the code. The key item has the code on itself, for those who don't use the guide as a reference or have the guide.
If you didn't check out the locked door behind Davowies Pub after beating the game, it contains extra commentary on the game development as well as bloopers from the voice actors.
Which character did you enjoy the most (for both voice and character - if non speaking?).
I am pleased you enjoyed the game in it's entirely. I've always enjoyed games that gave me a good laugh, have that cringe factor humor, breaking 4th walls, but at the same time as well have its serious moments.
Where you mind blown that it was Zarra the whole time, or were you not fooled?
I do remember playing Wizardry doing similar references (Ironic since the game's best spell is called that), hard game but it had it's moments.
There will be a third game in the series down the road when I have time to work on it. As well as I've spoken to David Camperman (The Narrator of the game), and he is looking forward to doing the "voice" of the Narrator in the third installment. Until then you'll need to ponder what future adventure awaits the Blue Wizard...?
