Sorry, there is not in the demo. That setting has been added for the full game, but unfortunately I don't think I'll have time to add it to the demo before we release. Sorry again for the inconvenience!
its ok, just hope to see the full version of the chapters with that option, i dont want to lost some view ones i start to play it
For sure. I've actually added a windowed mode option to the full game, so if you do play it on Steam, you'll have that feature :)
