You're meant to not find anything as far as I understand. Just try to get to as many "?" as possible before the timer runs out. There are 5 dreams to unlock.
Nope, beneath the 5 dream you can find a handful of other spots. When you found all , Eurydice says "I think we have explored everything". So you might want to give it another try :-)
yes, I'm aware, look at the comment I was replying to. My point was that the story is that you do not find the information that you are there to find. As far as the story goes, you look around until the timer runs out, that was my point.
Yeah, I though that too in the first run. But after trying again I saw that I must have missed one spot. To better track the maze, I worked with a screenshot (On Windows Shift-WIN) and marked every spot and trap ...
