This was a really well thought out puzzle game - I loved how the music tied into the comical chase scenes around the map :).
Well done!
To be honest I wasn't good enough at your game to get to the later levels =D. I got stuck for an embarrassing amount of time on the symmetrical level with 6 biscuits and 4 dogs and had to give up eventually. So I didn't hate the dogs that much just yet, but for the actual "chasing" part, the music works very well!
