Hello this is my first game jam and i just want to make sure I'm doing the theme right. I know we have to make a undertale fan game but how much like does it need any characters from the game, or just general feel, or just mechanics like the battle system. I'm sorry if my question was dumb i just wanted to make sure i understand the task.

it's not a dumb question, and also all it has to be is undertale related, meaning it wont require any of the characters from the game. Also you probably want a battle system, just doesn't have to be undertale.
