This was a great ol' time. It's completely ridiculous, lots of fun and super fast-paced and manic, just like you would want a christmas horror shooter to be.
I kind of wanted at least a little more context - like was Santa poisoned, and if so, why? And what was he actually shooting at the whole time or was the literal entire thing in his head? Just a little bit of clarification on that would be nice.
But still, it was a blast to gun my way through snowmen, presents, nutcrackers and rocking horses for Christmas. Good work!
