Hi everyone, I'm pretty new to making these maps, I have learned some things but I'm really struggling with replacing the Game Over music, and making an easter egg which starts a song.. I really hope someone could reach out to me for example in dms, or under this post, any help would be appreciated. I'll text the details of the things I need help with when someone replies.
Thank you

I thought someone made an tutorial about this but I guess it's not here.

If you know about how to add sounds to your mod, (I see a lot of tutorials about that) then you only need to add the following things to your soundalias file:

EasterEgg music
Game over music
Build your mod and you're done!
