Ive just beaten the three levels yesterday and the game is really really good! And damn i love that Krampus.
Another thing i really like is the music and i was wondering if there's a way to get it, i don't know if it's just me but is very catchy.
Edit: nevermind, I've found the music:
Werewolf theme: https://www.youtube.com/watch?v=bF67SfKGswg
