Fireboy & Watergirl Creepy Glitch

So, i was playing this game when i was 9, but i got a glitch and it repeatedly going over, When it finished, then a black screen appears for 9 seconds, and then it began to very glitchy just like in Parappa Creepy Haunted, and this time i got a jumpscare that was from AGK.Unzipped, and the flash player got crashed. Why this glitch has to do this to me?
