Nice work. I also had trouble with the dog physical movement and jumping, where the jump would send me backwards sometimes and the paws would barely move me. I was still able to complete the puzzles at least. Also had some problems where I started the game on the other side of the second door, I guess because I was standing too far away from center of playspace, and the key inside the lock box with the battery fell through the floor endlessly. Still a good synthesis though.
