Interesting idea and nice music. It's worth working on a script that determines what ingredient I want to take. It often happened that instead of a bun I took salad.
I also noticed that diagonal movement is faster than usual, this is due to the fact that it moves n-pixels to the side and up/down, when we should move by the square root of n-pixels if we want to move diagonally. There are many videos on YouTube on how to fix this.
It would be nice to increase the movement speed, but I didn't notice that visitors have a time limit, so it's not that critical.
