I have created a combination player-facing rules summary and character sheet. I wanted to title it "Electric Bastionland Milliamp Edition" and add a mock title like this:

However I realise this may be edging pretty close to copyright infringement... I ain't no lawyer is this ok under the rules on the jam?

Just call it a character sheet + rules for Electric Bastionland... I think that's what other folks have done.

Yeah you can call it something and then use the name Electric Bastionland in the description, but don't name it a version of Electric Bastionland or it will cause confusion.
