Since I'm going to be doing a lot of commented reviews, I'll keep it well structured by supplying you a reason with each of my ratings.
Game Design - 4 stars - The genre of game you made follows the rules at a very basic level so I can't give it a bad rating but I can't give it 5 stars in this category because it just feels too simple.
Fun - 3 stars - Level of fun I got out of it was pretty average. Not too bored, not too thrilled. However, this is mainly because I'm not super into these fast-food restaurant simulator type games.
Innovation - 1 star - I'm sorry bro but this game is a straight cookie cutter copy of all of the fast-food restaurant simulators you see on mobile app stores.
Theme - 4 stars - This genre is definitely a chaotic one so since you followed the rules of the genre so well, it fits the theme pretty well.
Graphics - 5 stars - I have absolutely zero complaints about the graphics. Very well-made sprites and effects you used for the wait timers.
Audio - 5 stars - Once again, I have absolutely zero complains about the audio. The sound design is pretty much perfect and the tracks were very catchy, fitting and entertaining.
Overall good game. If I was in charge of picking the winner, I don't think I'd pick this game given the idea for it was very unoriginal but I could definitely see it being in the top 3 or top 5. Good job! :)
