Love the mix of christmas and spooky vibes combined with the somber christmas music. 

The main menu looks nice and the achievements (great idea to add) kept me playing, almost managed to do the highest difficulty but would accidentally hit a present at the last second! Game seems well balanced and had no problem on easy or medium though.

I like the different movement options, I almost wish there was something that required me to make more use of the dash (its neat) like santa trying to run me down with his sleigh or something, but overall really nice. 

Art, Music and execution are all solid, nice work!
