Nice map - I enjoyed buying into the festive theme, and appreciate the work that went into this.
In terms of gameplay, Shades has put out other stuff that's more to my liking, and I felt the final battle was a bit too long and drawn out, considering the small size of the arena.
Still, the pd_style monster building was tastefully done - I appreciate that while familiar monsters behaved quite differently, it was consistent and not overwhelming/confusing.
