Very cute game! :) I liked the idea a lot, but felt it progressed a bit slowly. I also assumed that the + to all damage would include the gifts? They kept firing with damage 1 for me even when my santa-gun ho-ho-ho:ed away at 5 damage. :) So by the time I felt some need to get extra firepower due to the increasing number of enemies, that extra firepower was more or less useless since it fired low-damage and dissappeared very quick. 

I would love to play this again with a bit more time with the gifts perhaps and a bit quicker difficulty-curve. :)

The combat was satisfying though, really nice feel to it. Want to see what you do to it and get back for another run. :) A favourite!
