Achievement Cheer is a simple addon that plays a crowd cheering sound when you get an achievement in game. I made this to give myself a bit of an ego boost when I accomplish something in game and thought others may enjoy this as well.
It has an extremely low memory usage if this is a matter of importance to you and has zero configuration.
Are you going to add more sounds or in game options?
I currently have no plans to add more events/sounds or features like a gui. There are many, many other mods out
there that play sounds for other events like leveling up, etc.
