n-gon isn’t on steam, you can download it from github or play on https://landgreen.github.io/n-gon or https://cornbread2100.com/n-gon-loader

I don’t think we really need new categories because the speedrunning community currently isn’t very big and we don’t want the current speedrunners to be too dispersed into dofferent categories. If you have any ideas for new categories you could always suggest it in the discord server
