Thank you so much for the feedback! I'm glad you enjoyed the story and setting :)
The quest legend suggestion is great, I'll work on adding that in the next update! And I will likely add more save slots in the future and generally expand on the save system as I get more feedback on it!
The hair dye quest is actually the last main quest and the small quests after that are also the last ones available, so you didn't miss out on any content, but I should have added a "This is the end of the demo" thing in-game for sure!
