I was struggling a lot xD But I had a lot of fun! Nice concept.
I felt like each time you get caught, the whole level should reset, because the dogs not resetting makes it much harder the find the correct rhythm on how you have to move through the dogs, or you might have to wait for your window to move for a while if the dogs are in a bad position.
But except for that, very nice game, I had a lot of fun. Keep it up!
