Pros:

- Reminds me of old flash games i used to play as a kid in 2009-2013 and that one Mario 64 DS/New Super Mario Bros DS minigame about the snowballs called  "Snowball Slalom"

- The game looks aesthetically pleasing with the snow aesthetic, i think the the devs get the holiday vibes perfectly

Cons:

- Score seems to calculate in random intervals and isn't very obvious at first glance, to players, this basically means it's completely random

- Maybe change the angle of the mountain to be more straight (maybe in a small, short and sweet cutscene that changes the camera to be more straight), since i get dizzy after looking at it too long

- Doesn't have much replayability

- Needs better physics

Constructive criticism:

- I'd personally change the title, as this game doesn't involve killing, despite knowing what it's trying to say, i'd name it "Snow goes Slow" in my opinion as it rhymes better and rolls of the tongue

- Add a parallax scrolling background

- Song is too generic and gets repetitive after just a few seconds, (maybe make the theme longer and/or more memorable)

- Needs more consistency with it's art style (the snowball looks like it's from another game)

- Needs a Good original idea to keep players incentivized playing (Good example of games that does this: Balatro)

- Needs more items and abilities

Kudos to the devs for letting me in for a preview before the project was uploaded, i think they made an amazing job for being one of their first projects, cannot wait to see what they can cook! (and how i can help!)
