Hello and once again thank you for your suggestion! Unfortunately, we'll be declining this suggestion as we would prefer to keep Sledding as an exclusive winter minigame. While we understand that the game itself or the concept of it would be nice year round, we want players to look forward to the release of this game. In addition, by having it all year round, it would take away the seasonal charm and hype.
We hope to hear from you more in the future!
