Thank you! I've added some clarification on the game's itch page for now, but a tutorial segment is definitely in order.
Here's what I've added to the page for easy reference:
-Build sushi by placing nori first on the rolling mat
-Then add rice to the roll
-Look at the ticket to determine which ingredients to add
-Grab your ingredient, place it on the cutting board to dice.
-Take diced ingredients and add to your sushi roll
-When the roll is complete, grab the roll to roll it up!
-Place the roll on the plate, then ring the bell!
-Arrow keys to move the selected item
-Spacebar to grab or place a grabbed item
-TIP: Add diced ingredients in the order they show on the ticket! The top item should always be added first!
