Yeah, I exchanged words with them at one point many months back, and they agreed that they'd credit me and list the game's name in the description, which they did for a couple videos, but that has since disappeared again. I've been looking in to issuing copyright strikes, but I'm not yet totally sure whether or not those can be used in this instance. It's an issue I'm certainly looking in to though.
Thanks for notifying me though and thank you for your support!! I'm glad you enjoy the game :)
