Man, I really enjoyed the design of this game. Cutting the animals is pretty satisfying, and the game has a nice difficulty curve to it. The audio is also pretty cool and the cutting mechanic too.
apart from the idea of a high score, I think the game would benefit from a timer to serve the clients, to avoid "camping" and waiting for the perfect 0 risk opportunity. It would work with the theme of the game, as to not make the customers wait.
Another thing I would change would be the visibility of the order. the fact it is in the corner of the screen makes it not very "in your face" and forces you to shift your focus every order to that corner of the screen instead of keeping focus on the conveyor belt. Im pretty sure you could fiddle with different ways to make it a lot more "in your face" and finding ways to make it visible without having to shift focus from the conveyor, say a slightly transparent upscaled popup in the middle of the screen.
Anyway, awesome game and well done on contributing to the game jam!
