The author, Kevin Lewis, created a Twitter adventure game using SMS and Twilio on Glitch. The game replicates the gameplay via SMS, allowing users to send a Twitter username via SMS and receive their latest tweet as a response. The application uses Node.js and an online editor called Glitch. It sets up a Twilio phone number, receives and responds to SMS messages, and uses the `request` and `Cheerio` modules to read the latest tweets from Twitter. The game also includes features such as checking if the user is new and showing a welcome message accordingly. The author provides a link to their complete project and invites users to remix it in their own account.
