An engine for creating role-playing games using Twine's SugarCube language. Features a complex battle system that can be modified and integrated into your Twine stories. If you are interested in adding graphics or other assets, I have compiled a collection of free assets that may be useful.

When I first set out to make an RPG in Twine, I felt completely lost. I kept being told that many people wanted to and had succeeded at making RPGs before, but I could find almost no examples, and nothing that even came close to the complexity of other game-making programs like RPG Maker.

I want to change that. I made an extremely complex engine that can do pretty much anything RPG Maker can do, and I've made it completely open-source so everyone can see how it works and use it in their own games.

If you're an RPG designer, I'd really appreciate it if you could take a look at this, give me feedback, and pool our resources. I want to make this as accessible and powerful as possible so no one has to reinvent the wheel anymore.
