Ok, your game is more arcade based. Just a idea. How about you make it like a arcade game, like when you want to start up the game it asks for a coin, and you press enter or smth to start the game. And like you have your game housed inside of a game console. Imagine at the end of the game the character that is playing the console stands and says, "I'm parched, I'm going to get some water." Then roll the credits.
