Wow, “finished” the game with more than an hour left. Very simple gameplay, but at least playable in a couple of minutes (I hope!). Note: This version require that you have python and pyglet installed. Read the readme.txt! I will hopefully be able to make a py2ex’d version tomorrow.
The game can be downloaded here: Snowroller download (2nd try)

edit: Papper found a last minute bug that Ive fixed (within the time.) Now it is the final version (really!).

First screenshot. We can see snowballs beeing pushed away with a explosion (notice the great explosion animation) and that is all. Now I only have to put some gameplay in this game and it will rock! As I have used pyglet and pymunk for this game, the little code Ive written myself is almost nothing, but that will change now when I have to make it playable…
