That was clever! The logic-grid puzzles are engaging, and the character art is charming. It's a little rough around the edges, but with solid fundamentals.
Given the other comments, I'm probably a serious exception in this case, but I found the difficulty to be trivial after learning the main combination of rules and prioritizing the easiest ones first (exact placements, required specific items). I was always at maximum mood, and could've potentially gone endlessly. It probably still starts a bit too difficult for a beginner, but it'd be nice if the difficulty continued to escalate in some fashion for higher skill levels. Mood restoration might also be a little bit too powerful in the late game.
All-in-all, great work!
