Ohhhh I see I see-- totally get that inspiration! I think at least from my perspective it felt like I was on the customer service end rather than the customer end, so it felt like if I made a mistake interpreting what the customer wanted, I wanted to be able to undo my mistake or remove the piece of sushi. There was also kind of the funny aspect of realizing I messed up and having to submit the plate anyways which I did laugh about, but to me at least it felt like it conflicted slightly with the narrative.
As for other suggestions I think the only one would be that sometimes you're given two orders that are impossible to fill which can be frustrating. Maybe you'd be able to do a check before assigning an order to make sure it's possible with the current sushi available? Or if you add a way to discard/remove sushi from your plate, then you'd be able to refresh your options until you can fulfill the order.
Regardless of all that, it really is quite fun! Such an impressive amount and quality of work in such a short amount of time!
