For the first assignment game controller with HID output, I chose to make a controller for this version of the Lunar Lander game:

To play this version, the users have to press the up, left and right key, and the mouse.

For my design, I implemented a controller that is a combination of sensor and buttons. More specifically, Adafruit BNO055 absolute orientation sensor to control the direction. Two buttons, one button for mouse click and one for the up key.
