This reminded me of a mobile game!
Like others said I thought the art direction was very nice. The sfx and music were simple, but I think it helped convey the tone in a great way.
I did think it would feel more intuitive if the dogs could also pick up presents, it took me a bit to realize that the sled itself is only able to pick up the presents. However, once I got farther in, the rogue-like quality was very fun to experience.
