juyeonk – Final Project

For this project I wanted to create a game, but not one of those kinds where you feel anxious and competitive while playing the game.

So I created this game where you can enjoy the winter scenery and a cute dog running while given a bit of an entertainment of being able to move around the dog and its sled to collect the presents.

How to:

Use the left/right arrow keys to move around the dog and its sled.

Use the space bar to generate more presents (will be falling from the sky)

NEVER HOLD THE KEY DOWN!!!

The sliding motion of the presents was to re-enact the real time inertia of the objects.

Yes, I am aware the snow is going upward and Yes I did that on purpose.
