Okay, played a few bad puzzles, got a bit more inspiration and motivation.

So, how do you make a bland puzzle more frustrating? Why, add snow, of course! And not just any snow! Make single dot snow! Now your puzzle will become bland to bad! Congratulations! Here's the Snow Edition of Frustration!

Honestly, I don't know how to give efficient hints for the snow that would make sense... So, like the Christmas cheer the snow brings, I'll give you all the snow pieces!
