Loved the game, but I think there are a few things that could change for the better. First of all, when I was killing hoards of snowmen, some of the dead lumps of snow would get in the way of the bullet, not sure if this is intentional. I also noticed the dead bod of krampus was slowly sliding along the ground. Lastly, I was a bit confused on what letter corresponds to what gun, I think it would be better if there was a simple chart or some kind of different icon to represent the gun better, rather than just a letter.
Besides that, I really enjoyed it!
