I've seen it a few days ago, I don't really have a problem with it. It has some minor changes and added features and the person who made it atleast mentioned me in the game description. The character Eyeless Jack by himself does not belong to me either so I don't really care. But thank you for letting me know!
Yes, I know the Creepypasta doesn't belong to you, I just find it great that there are still people to fuel this community! But this game on Roblox is straight just a pure copy, that's why I mentionned it. But if you don't mind, then there's no problem. Keep up the good work I'll be glad to try more of your work :D
