It doesn't have plot. That's fine, not all games need justification.
The graphics are pretty weak and the background just cuts to white after a while.
The gameplay seems to be a rip off of doodle jump-style games and not a particularly good one at that. The gameplay does not change at all, there is no ramping difficulty or different kinds of snowflakes.
The music is fine. A bit repetitive, but fine.
I think this game could be something good if you extended the background, added ramping difficulty, some variety, and above all, a GUI.
Give us some indicator of our current score during the game. Perhaps a height indicator as well. These would make the game more exciting and give more motivation to keep playing.
As it is, this game is not particularly good.
