Your art style and music choice is wonderful! Unfortunately, I didn't find the gameplay that enticing. This being said, I could see the potential for this to become a mobile game if there was a bit more fluidity of movement for the dog and if the gameplay advanced as you worked up a high score.
I apologise if this is too harsh a criticism, I do like your design and I think that that is something you need to keep going forward with this project or other ones. All the best and good luck in the Jam.
