I liked it!
The angry birds theme has been milked enough, but this is the opposite where you're trying to save the pigs so it's refreshing.
There were a couple of puzzles that left me.. err.. puzzled but that's why I liked it, nothing was straightforward (except for the tutorial which was very easy to understand).
The artwork was simple enough to enjoy, there wasn't a lot going on to draw attention away from the puzzle itself which can be taken both positively and negatively, the music was enjoyable for a few minutes but then I had to turn it off, sorry about that, but I'm glad I had the option.
I really liked that bonus level, why weren't there more?
If you make another, let me know!
..Now I'm off to consume the bacon I just rescued
