OK, I managed to complete the Tutorial Dream playing solo without too much trouble, once I worked out how the rules flowed. (Though watching a playthrough after the fact, I noticed that I'd entirely missed finding any items. I hope that doesn't make things too difficult later.)
Playing on, I keep finding questions that I'm not sure I can answer correctly from the rules. The rules seem to make a number of assumptions (I guess that's covered by the note regarding "obvious" rules, but having played so many games where the rules are pedantically specific, and assumptions will get you in trouble, "obvious" may not be the same for me and the game designers.)
First a minor point. Though I appear on the "Awakening" spot on the Dreamworld map, the "Awakening" Wisdom card is not related to this? It appears to be something I can use at any time later to change characters. So if I don't use it now, I continue in whatever state I finished the last dream (in my case, luckily, no Distress and just one card sealed). Is that right?
Moving around the map, I turn over Fate cards and Slumber tiles as directed. My first Quirk card gets me to place a Dreamscape map tile, which doesn't physically connect to the existing Starting tiles (except at a corner) and place the Quirk card. Is it a problem that there are now separate unconnected segments of the map? I'm not sure the rules exactly say how Quirk cards work. I assume it triggers when the Time card has a matching action, just like for any active entities, even if the Quirk card is on an unconnected section of the map.
Next I draw a Slumber card that spawns a Wraith. (The first slumber cards I drew ended immediately as I didn't meet the conditions on them). So I guess that means I now enter the slumber with that Wraith (another "obvious" rule, I guess). I guess I could enter on a different part of the map to where the entity spawns, but that would be equivalent to Skipping the Slumber as we couldn't interact and we would just time out. I don't yet know what the penalty for skipping is, so I'll just leap into this slumber, and see how it pans out.
I guess this will all become second nature after a few slumbers and another dream. But a little more guidance would be nice when starting out. I'm enjoying it so far, but it's taking me such a long time with searching the rules at every second step. Maybe I should think about writing such a guide when I understand it all a bit more.
I too had this question. If you found the five items, I was under the impression they went into the Storage. After the completion of the tutorial, I was confused if all five items went back to Storage (from which you then "restore" three random ones) or they were supposed to go into the Item Market.
