A game engine, a live editor and a debugging environment (IDE) for browser based text adventure games.
You can try out the IDE loaded with a sample (dumb) game at https://gauchedroite.github.io/teller-man/index-ide.html.
Everything is written in TypeScript and LESS.
Only npm scripts are used to build the app. No fancy webpack or gulp scripts involved.
See the Wiski for more docs.
