Thanks for the suggestion! We do have a key skin update in mind, which will be implemented in the future, but it will be on the back burner of new content we're working on. Please be patient and we'll bring you better content!

Thank you for taking my suggestion into consideration, as there is a sfw mode for the game, maybe some who will come across this game and also enjoy other rhythm games and would like to stream it and could create a larger audience for those at the appropriate age. I really enjoy the game and still getting use to the key binds since I'm use to playing Friday Night Funkin Mods. :D
