Thank you!
To be honest I wanted to make it a bit more in depth but due to time we ended up using a keyword system. Since progress in the game is tied to knowing certain words, we tied that up with specific triggers for the messages that unlock them. So it's a very basic parser that just looks for those trigger words to make progress. Of course, there are other trigger words that return flavor text, then there's the commands (which also have variations internally), and we tried including some easter eggs in there too! (which I would have liked to include more but was running out of time!)
