Minor changes

A few quick changes I’ve made over the last few days: my brother suggested adding a button to disable certain in-game elements—such as the intrusive messages that appear when you complete a level, the player level-up notification, and the alerts that pop up when you pick up power-ups, experience, or speed boosts. I’ve now added an option in the advanced graphics settings labeled "remove special messages," which suppresses these annoying, distracting pop-ups and helps maintain a smoother flow of gameplay during the waves in each world.
