Currently I am working on a Machine Learning AI with Unity Machine Learning Agents. It is my bachelor thesis, where I build a game in collaboration with Daniel Schellhaas who provides me with the art assets and then work with machine learning to create the AI. You can download the full project in its current state here: MLBF-Project (15 downloads)
Please be aware that this is work in progress. You will need a controller to play this game and can play with up to two players.
