Super cute art and music. I like the idea of using the presents as part of the platformer puzzles, that made me stop and think a few times before inevitably screwing up anyway :D
The story is nice as well, and knowing that you're meant to use the "goal" to achieve the best possible ending makes the second playthrough a lot easier. But the ending screen prompt when you don't get all the presents already encourages players to go back and try again because surely no one would want to ruin Christmas!
Solid entry, I'll be thanking Crimbo come Christmas
