I would definitely class this game as "short and sweet", which is not only welcome, but actually a bonus considering that it has some replayability in the form of a randomly-selected present required to help Santa. The achievements board after completion was a nice extra touch, and I was simultaneously annoyed and impressed that save-scumming didn't fool it! A couple of the puzzles weren't so intuitive before finding the solution (if that makes sense?), but I didn't have much trouble solving any of them just by trying everything that I had to hand.
Also, your graphics set the scene nicely, despite their low resolution, which is quite a feat!
