Thanks for the feedback 😊.
There's a tutorial page but you have to navigate to it on the menu, it's the 4th button below the soundtracks. Though, I'll probably have to make it so that it shows when starting a new game.
As for the assist, I'm assuming you mean the prepared food? You can cancel it by pressing again on the plates, which is also in the tutorial page.
I'll add the tutorial when starting s new game on the next update 😊.ñ
