This is a classic snake game, but it has a few extra options to allow customization. It allows the player to change music and toggle sound effects. It also offers a few game options like the ability to wrap walls and "party mode" where the colors change.
This game originated from a tutorial but as I was creating it, I saw things that I wanted to change. The original tutorial had it wrap walls (snake doesn't die when hitting the wall, and instead wraps to opposite side), and the snake games I used to play always had the walls trigger death. I also used the opportunity to create my first ever menu system in GameMaker.
