ENDLESS_RUNNER face
This is a basic endless-runner, like the [Chrome Dino game](https://en.wikipedia.org/wiki/Dinosaur_Game).
On the title screen, you can select a difficulty by long-pressing LIGHT or toggle sound by long-pressing ALARM.
LED or ALARM are used to jump.
High-score is displayed on the top-right on the title screen. During a game, the current score is displayed.
