I saved Christmas! Haha fun little game, I was trying to time the drops at first I didn't realize they automatically aimed at the next available NPC. I would maybe try to make that a little more clear. I also didn't understand what the top right 'gift' bar was at first, but might be on me. It started pretty slow which is understandable, but I didn't know it was going to speed up and almost quit out early. IMO you should try speeding it up a little sooner to the start of the game. Just my opinion but the NPC explosion animation was a little grim lol, some tonal whiplash between that and the super cute Santa animation, but that is probably the point I guess.
Honestly I would speed it up a little, maybe a bit more polish on the NPC's and differentiate the Naughty vs Nice ones (Give the naughty ones stereotypical leather jackets and smoking or something? Make it a little more absurd :D) and maybe add some alternate xmas songs. The Santa sleigh animation was really cute, I liked that!
