I had a lot of fun playing this game. I loved the way you and your team implemented the special object and made it something essential to the game. I also thought that the idea of playing a minigame to repair your sleigh was pretty cool.
However, I encountered a few problems while playing with the first of them being that the bell mini game never ends. The second was that after the game announces what place I came at the end of the final lap, The race would not end. Instead, it just continued forever. The third and final problem was something that I'm not sure was intentional or not but, the sleigh takes damage all the time even if you aren't making contact with anything and aren't moving. Though I'm not too sure whether or not these problems are exclusive to the WebGL version of the game.
Aside from these few problems, the game was great. Your team did a great job and I definitely think more people should play this!
