Hi,
is that a bug or intentionaly that you can enter the wireframe world as Dolores without finishing the other characters' story arcs? I only realised that I missed out on a lot after reading the forums while watching the credits roll. Tried to load the autosave, but that one was already in the wireframe world - and you can't swtich characters back from there.
One should consider adding at least a warning box when the player attempts to use the ballon animal.

I found it pretty obvious that you should first finish all other character's storylines.
The game even tells you so, Chuck says something like "here's an item for everyone to finish your story and then you can destroy this world once and for all".

I agree that it's a bit "open" letting you go to wireframe world first, but I think the warning is right there. ;-)

Well, at the end we (at least "I" still don't know what exactly happened to Dolores' father and the german guy (or was he french?)). We have a suspect who obviously was sleeping drunk at the time and we know who organized it. But what happened and wher is Dad's corpse?
