If you put anything other than undertale, it will be unfortunately be deleted. This can ANYTHING related to undertale, such as fan games, simulators, ect.
If you ask in the comments, you can be any monster or character (Including fanmade characters) that haven't been taken. I'm Geno (aftertale sans) so don't ask for that one.
