This lesson will introduce a title screen. The intent is to introduce separate "scenes", and the transitions between them.

Pressing a certain button on the title screen will begin the game, and a Game Over will kick back to the title screen.

• First, please propose an implementation, and send it in as a draft pull request (see step 6 of this guide for how to do so). (Maintainers can mark it as draft themselves afterwards, so don't worry.)

  The PR will be reviewed by one or more people, and you may have to modify your implementation based on their feedback.

  After a maintainer has greenlit your implementation, you can start writing the tutorial text, which describes the implementation.

  Once the description is fully written, please mark the PR as "ready to review" to signify as much.
