The audio in it was great, kept it relaxing while I was rushing to make orders lol. One thing of feedback I can give was for the camera position, as when I put the drink on the second tray, I couldn't see the chicken burger item behind it for the next order. Other than that, great job!
I think the pacing needs work. You just endlessly assemble the same meals over and over. It would really improve things if you had some goal to reach and a few levels with a break between each. Maybe you could add new ingredients in each level. Also, the meals need to start coming in faster and faster. One could theoretically play endlessly if they can assemble meals faster than ten seconds.
Still a fun entry. Nice work!
