I've had some trouble with figuring out where exactly the presents have to drop. It seems that hitting Santa is not counted as success, but aiming is pretty hard. Also there could be better feedback on whether you succeeded or not (by sound effect, for example). So it felt a bit like a guessing/luck game
The visuals are simple but they work well, and the music fits the setting. I guess you chose "Mistakes Were Made" as the theme?
