I couldn't progress past the second piece of metal for the radio. The crates stopped spawning to shoot down. I tried to reload the game, and "continue" but the problem persisted. I'm not sure I got far enough into the story, but was Krampus the big Gumby lookin guys, or the skull in the sweater?
Either way, execution is decent! I like the aesthetic, I like the snowmen. The intro is nice. The gun aiming was a little off; sometimes it would aim down sights, sometimes it would flicker. The cold mechanic is well-implemented.
Solid attempt!
