Thanks for all the positive feedback guys! I really appreciate it and will continue to make more content like this
I had prismstone before this (had some technical issues lol, but fixed it) I had a cat sound, now it is nyan cat sound. Much Rainbow Lazer very Nyan Cat
Its a okay mod but if you have brimstone it can get really annoying after a while.
