texty # texty
An extremely simple text-adventure game engine(?)
## What is this?
I was bored
## How do I make a game
Check out the `example.yml` file, all games are in the `YAML` format.
## How do I use this
Download/clone the repo and run the `__main__.py` file with the path to a game in `YAML` format as the first argument.
## TODO
- Colors
- Catching errors while parsing YAML
- Maybe a welcome screen instead of the need to enter the path as argument
