Game Updated

With winter coming up, I found time to revisit my very first game created with this engine, and I decided to update it. Penguin Snowball Fight now plays a bit smoother, with optimized collisions, and it's possible to upgrade the snowball weapon multiple times to shoot more, larger snowballs, faster and more frequently! The score is also registered to show up correctly on game over - can you beat my best of 87k? I'll probably add music and more sound effects later on.
