you cant make screaming
BUT
you can make a noise
make sure you dont make a loud noise though because that could be bad and scare little kids who might stumble upon your game in their free time
theres a couple guides and questions with answers (sorta) on the forums that you can use so let me find some rq
1 ) [Mini Guide 🤏 ] How to make a Sound Cue!
2 ) Music in GKC, possible? (partially solved) - #3 by NotYoyo
