It's certainly creepy, and I liked the vibe of the game. But I felt like I had no idea what the goal was, or how to attack properly. 

I think with some more telegraphing in the game it could be pretty great! Like opening with a general guide of what to do whether that's just killing things, or searching for Santa. Also, having an attack without needing to use the mouse would be great. 

Well done!

Great scary sounds and darkness effect! Nothing like creepy christmas !

Next time I would suggest throwing in an attack animation so I know when and where I'm attacking. Also, instead of instantly restarting when I die, a little death animation or  "you died" text would go a long way in making the player less frustrated.

I like the horror theme on this somehow, but it is a little strange that you don't really know when your ability to hit is recharged. This makes you sometimes run into enemies thinking you can hit them and you simply die.
