I think it is time to do an update on the DODO list:

• [DONE] Try audio support with the buzzer
• [DONE: board in production] Some improvements to the PCB (on/off switch, button position)
• [DONE] Add an API for persistent storage (highscores, player data)
• Add an API to read the accelerometer and magnetometer of the micro:bit
• [DONE] Improve performance of screen data transfer
• Design a case for 3D printing

New item:

• Create an example game/project that demonstrate all the features
