This tool can be used to create simple DES files for minihack environments.
Firstly install the node version manager
then run the following command to get the latest stable version of npm/node:
nvm install stable && nvm use stable
After we have the latest stable versions of node and npm installed, we need to install the dependencies for the level editor tool. We can do this with the following command:
npm install
Finally we can start the server locally which hosts the level editor tool!
npm run start
This will start a local server on port 3000 which you can use to access the level editor
