It took me so long to realize that I could eat snowballs to recover my health, lol. It was hard to tell when snowmen hit you, but other than that, it was a fun experience. I'm used to playing FPS games without crosshairs (for ~immersion~), so no problem there (but I understand some people prefer them, of course). The snowball mechanic is pretty sweet, and nice detail with the horns (it helps with immersion, hahah).
Also, maybe it was just a browser thing, but on Firefox the camera starts moving slowly to the right as soon as I start moving. I had to play on Edge instead.
