I was a huge fan of the curved screen affect! If I had one minor note it would be that the presents always move relative to the chimneys/houses rather then the sleigh (which means you can place your mouse at the height of the chimneys and click whenever a chimney touches your mouse to greatly improve the chances of you landing the present). I feel like it might be interesting fro a timing perspective to to have the presents move with the sleigh. That being said, it was a lot of fun and the pixel art was very cute.
