Well I'm slowly but surely making it through the puzzles; Currently stuck on level four (figuring out how to turn the water on and stuff), but I'm still kicking. Overall I really like this game! The puzzles are creative and the duck theme is adorable and works well. Art style and animations are very cozy and well-drawn like a children's book. The only thing I would say is to make the little hint device more clear, whether that be through clearer instructions or more detailed drawings, or both. For instance, if you have to leave the room for the puzzle to progress, maybe hint toward it on the device or in the area.
Great work!
