"Hack the Bubble" 2021 - an arcade-themed, 12-hour hackathon arranged by STACS (St Andrews Computing Soceity).
The initial idea was to implement an AI making use of Reinforcement Learning (Deep Q-learning) to learn how to play tetris and beat it. After suffering numerous problems with this side of the project, we just decided to write a few arcade games.
Done in Python 3.8, making use of the pygame module. See here for a good example.
