Hello, I would like to suggest 2 categories: number 1: 100% Number 2: epic balloon escape ending

Hi! We are already working on the 100% category, it is not yet known when exactly this category will be released. Be patient a little bit!

Isn't adding a category pretty easy?

Not really, no. Categories are usually added when people actually present them with a finished run, according to what they think makes sense for the category being requested. Rules around something like 100% would rely on people to agree on what 100% even counts as.
