For the corridor that needs neocash keys, I suggest reading the FAQ
From what I've gathered so far...
Each Brozne Peg represents something that you have to move by opening the doors.
The stone slabs are trap squares and stun you for one 'turn',
apart from the one with the golden key on, and the one with icecream on, and the Usuki Dolls.
There is a golden door on a floor, which you need to get a peg to.
And the weird things at the bottom appear to control the doors.
Ok this is more simple that it seems, each thing at the bottom controls the doors, you set the sequence of doors you want to open and it will open them in order, allowing your peg to move from room to room. i.e... Two different colours of doors will never be open at the same time. So basically if you need to pass through the following doors in this order, say, G,B,R,G,B, you set the knobs at the bottom to that order and it will open the doors and your peg will move through.
If you have more than two doors with the same colour joining a room, its a little bit of trial and error, I have not yet noticed a way to pre select the door you want it to go through. You will just have to cycle around the rooms until you get the right direction, which is so annoying...
Concentrate on one peg at a time and it is much easier... I suggest getting all your pegs to form up in one space, where they join forces and then you only have 1 peg to deal with.
We All Scream
Everyone loves an ice-cold bowl of Chintzy Mynci... even Hubrid Nox.
-Awarded by getting all pegs to the icecream slab/trap, I did it by getting them to all form up and then went to the icecream room, then I got the acheivment on completion. (as in when i left the gold doors)
There's gold in them thar halls!
-Find the treasure (not marked with an icon) in one of the rooms. This may take a lot of wandering about through all the rooms...
And One For All
"After you." "No, after you." "No, I insist! After you."
-Awarded by exiting through the gold doors with all three characters together.
And as with the last chapter there are some bonus items to be won.
Hubrid Nox Treasure Chest and Giant Tub of Ice Cream
Playing with the Treasure chest gives you items, unsure what the posible items are, but there you have it
And... Sorry, i'm trying to solve it all atm, so i'll add more when I'm done.
Edit by noit:
Once you get all the pegs togather the exit is the GOLD door not the green one. See attached image.
