I know this is a demo, so this might not be a bug, but I thought I should point this out. I completed the first quest, went back into the forest and lost. I exited the game, came back and now I cannot enter the forest. I click on the icon, but nothing happens.
Same problem occurred to me. Completed intro adventure. Did some more adventuring to grind gold. Exited with [esc] clicked yes when asked if I'm sure. Tried logging back in and cannot click woods icon. it does not highlight when you mouse over it. Will work if I start over again, but when coming back after exiting same problem.
On a different tack the treasures/interactables in the woods don't seem to have consistent activation spot to click. Sometimes I give up and continue through woods because not idea which pixel it wants me to click on.
