Like Kevin comment, I think I made it to the “end” minus whistling. Not sure what I missed, but it’s a fun interactive puzzle game and I would love to see more strange situations like this with similar mechanics. Maybe a story adventure, where you start out having to do this character’s morning routine, brush teeth, tie up shoelaces, etc. Eventually they find their way to this silly situation, stuck in ice. I would love a full puzzle adventure with this style and atmosphere. Great game!
