Thanks a lot!
Yeah since im mainly an artist i overestimated my ability as a programmer haha! There was supposed to be a nice tutorial but we ran out of time to implement it in engine. As for the copyright i messaged camellia himself an to quote him "I usually ask most developers to get the right licensing for using my music. But since it's just for a game jam, I won't stop you from using the songs for now." - Camellia, He also said to get proper licencing done if we want to do a fuller release.
Glad you enjoyed our game!
