Ah yes. I have received feed back that the quest system, while it works how I intended it to, there's no feedback as to what you are supposed to do. You don't have to help the gardener first, but you do have to talk to the child in order to pick up the medallion and you can't be on any other quest, so if you had already talked to the gardener, you can't accept the child's quest until you complete the gardener's first.
But thank you for the feedback and I will definitely try your game when I get the chance!
