I'm afraid I'm stuck and can't complete the game. (and yes, I deleted all old versions and old save files before installing the full version)
(no spoilers, of course)
It's the section towards the very end where the text ends with the phrase "Is that what I think it is?" Basically, I've found everything I need to find to get to that text box, but then I click, the text box disappears and I'm still just... in the same area and can't progress. When i click the main area, the same dialogue just comes up over and over. I keeping clicking everything where a magnifying glass appears but nothing progresses. I've exited and re-loaded from previous save points, but the same thing keeps happening - even walkthroughs I've looked up tell me I haven't missed anything.
Is this a bug?
EDIT: I finally finished the game! I came back to it a month later, and, I dunno why but it worked. GREAT game. Everyone should give it the 5-star review it deserves!
