I love the concept & style! I agree with Cocolito that the background being alive is super fun & engaging! The only feedback I have is maybe add a bit more spacing between the platforms (or maybe a separate difficulty level) because the level of precision needed is a little frustrating, especially once you collect a few items and the items obscure the paw location. It helped once I turned my mouse sensitivity down but it pulled me out of the game. If you still want to keep it one single game, maybe have the platforms start widened, then as the player fulfils more orders and gets used to the control, tighten the platforms and add the top row. Another option would be make the hit boxes on the non-pickup items a tad more forgiving. That said, I enjoyed the game and I wanted to play it more because it is such a novel idea! Seriously awesome work :)
