I wasn't really aiming for making it difficult, just a small cozy game as you walk in the snow. I think adding more content would have made it a little bit less boring.
It was fun. You added the warmth bar mechanic and a destination so my immediate assumption was that it would be difficult to keep it up at some point. The game was really good for a game jam game! The warmth bar communicated to me that I have a goal and meeting that goal might introduce challenge.
