Hey Nadia!! This sounds very fun to play! Maybe you could implement overlays like the ones used on TV News channels with text scrolling right to left. This sounds like a Food Network TV series!😊 Maybe commercials too?
Also, you could make simple cutscenes with judges eating the sandwiches. You could make separate animations, depending on if a variable is less than or greater than quality, you get a different reaction from the judge. Then they could pull up a stick with a number for the rating for each category. Maybe use a float variable for decimal values.
For simple mechanics, maybe drag and drop tiles. Say you drag a bun to the table. The tile disappears and the bun appears on the table. You could make the ingredients required in a certain order. You might want an area where you can resupply missing ingredients to a bottom HUD.
You might need lots of SetActive(false) and SetActive (true) to turn objects on/off if you're using Unity.
I could see this being a light version of Overcooked! and Cooking Mama! I was having trouble myself relating this to a TTRPG, since my game is a stealth RPG. My ending will include a paradox of people playing the game I made as a board game, all within the same game 😊
Good luck!😎👉👉
