So,  I've found a couple different options for getting Itch into RSS feeds, like this one for getting notified of new games:

http://itch.io/feed/new.xml

Which can be modified into this feed for getting new games from a specific creator:

https://itch.io/games/newest/by-stepnix.xml

or this format for a single game's devlogs:

https://stepnix.itch.io/dragonslayer/devlog.rss

But I'm not sure if I've found all the possibilities yet. Is there a full RSS guide anywhere that can be easily referenced?
