Sorry I'm late. I was working on SCRAWL (Solo Crawl), my solo RPG game which involves exploring a whole world with settlements and dungeons and everything else. The plan is to release small gamebooks every month using the SCRAWL rules that you can either play stand alone or as part of your crawling.
I've currently done the core rules, the rules for wilderness hexcrawl and the rules for settlements and sites. I need to finish the dungeon rules.
You can see how it is progressing here:
There is a Facebook group where you can also see some great SCRAWL illustrations:
There is an old version of SCRAWL on DTRPG: DriveThruRPG.com - Slloyd14 - The Largest RPG Download Store!
