Really nice little game, give of the vibe of a "Pacman with physics"
Having more robots dogs with differents AI would have give a lot to the game, like in the original Pacman, Blinky actively chase the player wherever he is on the map, or Pinky and Inky, try to place themself in front of the player.
I also probably don't understand correctly what's the point of returning to your home to increase the multiplier ? As it does not scale with the biscuit you bring back, and when you finish a level, it does not increase it ?
Anyways, really nice game, it was fun to play it ! Continue to creates game like this one ;)
