Early development screenshots

After some days of development, some basic game milestones have been reached:

• Human controls of player 1 (and player 2)
• NDS controls NPC players (player 2, 3 and 4)
• Snowballs can be thrown by human players, collission detected and score updated

Here come some early screenshots (note: some colors are wrongly displayed in Dualis but work fine in the real console)
