I was interested in making a live game like Twitch Plays Pokémon from years ago. I recently saw the Falling Pickaxe game trending on YouTube and decided to go for it as a small project. I had already made a Chess game and thus had some code. I made this version by integrating the YouTube Data API. Game engine is Unity. Moves are checked every 20 seconds. The underlying AI is Stockfish. It falls well below the api quota and can be run all day.
