This is a fantastic take on Santa's operation portrayed as a commercial business, but with the added twist of cyberpunk which you've somehow made fit perfectly. I was a little disappointed that there doesn't seem to be more than one way to end the game, given the circumstances. Perhaps there is, and I just didn't find it, but the responses that the game gave me to my attempts made me think otherwise.
It's a very small thing, but the grading system is confusing to me. I got an A rank on my first playthrough, and on my second playthrough the only things that I consciously did differently were to go faster (obviously) and to deliberately leave my vest at the delivery point, but this time I got an S rank. I had imagined that getting a better rank would involve doing something significantly differently. If leaving my vest behind was the key, the epilogue didn't seem to change in any way to indicate it.
Your graphics made good use of colour, and details were picked out recognisably, adding impact to your text descriptions.
