Fun little game, great job! A couple suggestions: I thought the 'calm' part could be a bit longer, especially in the beginning, so that the player can read the upgrades as it took me a couple waves to see what all the choices were and decide. Also, it would be great if there was some visual result and consequence within the game of upgrading the decor and food of the restaurant! Like maybe instead of losing when you fail to ward off a pirate, it decreases the amount of customers you have, and the more you upgrade your restaurant the more customers you get, and your goal is to get as many customers and make as much gold as you can! This way the focus of the gameplay is more integrated with the restaurant concept (since currently the gameplay is just based on warding off pirates, the restaurant concept seems like a bonus/not as related)
