2B or not 2B ?

I tried making this after i found one in the store where the typing audio had noise. I'm not sure if the assets i used in this are copyrighted, and if so, whether my use of them is legal. please dont sue me. If you are the owner of those assets just contact me ill take it down. ಥ‿ಥ (Contact: crimsonoynex@gmail.com)
