Little Games has already said most of what I have to say. I didn't finish the game, but the game is sure as heck beautiful. One thing i would like to say is It lacks UI. And it is quite short. But the models and the game itslef looks very peaceful and good. Like LittleGames said, it does not match with the theme.
And a suggestion, you could've added a menu to change the colors of the sleigh and other stuff. Of course it would ruin the christmas feel but at the ame time give more depth to the game. And also powerups could've been added. One thing i forgot to mention is that the camera movement is lovely.
I didn't submit a game, so I can't rate. But if I had to, I would give it 6.5/10.
Sorry for the harsh rating, but the game can be bland and boring. It possesses serious potential if you continue to work on it and make it an endless runner game. I would for sure love to play it.
Overall, the best part is how beautiful it is.
