The concept is simple but executed really well. The graphics and the music help really build a very aggressively snowy atmosphere that I think helps build a lot of tension and urgency to escape. The only thing for me however is that maybe the control scheme could be adjusted a bit as I do think it is a bit difficult to play with for me personally. But I also think this might be because I am more used to using the arrow keys + "z" and "x" when playing platformers with my keyboard. With that being said though, I still enjoyed the game and I think you did a great job with it.
