I love the art style you have going here! As a simulator I think it captures the repetitive nature of minimum wage jobs quite nicely. I found it relaxing to play. I wonder if the music is the right choice? It's unclear to me what vibe you were actually going for. The music almost makes it feel like an action game, which I don't think it is, but I could be wrong if that's what you were going for. I think this could work well without the timer or score if that's something you are interested in exploring. The look and feel is able to stand alone I think. One idea might be to have this be a secondary game to some kind of larger narrative experience. Also the way the score is implemented right now you can just spam caps on the same cup to raise your score. There's a lot to build off of which ever direction you choose. Good job!
