Interesting concept! I couldn't get it to work in a way that I felt efficient in the kitchen, so I guess in a way it was realistic since I am not a great chef at home lol.
Haha. I found that the echo isn't very good at cooking patties (it takes too long for a single loop), and it was best to let it do the veggies. I think in a more polished version of the game levels would require you to use multiples echos together in creative ways to meet some kind of cooking goal.
