That's the most content I've seen in a game jam game in a while, congratulations! Everything oozes "handmade" and I loved exploring the world. I was very impressed with the quest system and all the little interactions that you made for each quest. I can't imagine how much time it took to make the entire level, and also the sound! I have a feeling I skipped some of the side quests though, if there were any.
The core mechanic of the flute wasn't too engaging, but I guess that's to be expected of a cozy game. Would have loved to have seen more ways the flute could be used. Also missed opportunity to have sound for each flute technique. I fully expected to hear some jingle whenever I pressed J, K, or L.
