The project ConnectFour can be executed with the file "src/GamePanel.java" via IntelliJ (or another Java IDE if compatible) or by using the JAR file located in "out/artifacts/ConnectFour.jar" along with the following command: java -jar ConnectFour.jar. Furthermore, this JAR can also be found under the Releases.

NOTE: The original repository with commit history was hosted on my project partner's GitHub, which he no longer has access to. This repository is to serve as a public version of the project, viewable by others, without the commit history.
