The plot is kind of meh, is the floor frozen, everybody(including the zombies) is on skates? Why has the player character a helicopter blade belt? I feel a missed opportunity here, the mechanic could be incorporated into the plot!
The colors for the text - not the best, the dark gradient kind of blends into the background making it annoying to read, paragraphs would be nice too.
The game mechanic is ok. There's a bit of a challenge, but it starts easy so that's fine.
