+About: Setting up a Vagrant virtual machine for this project offers several benefits. Firstly, it allows for easy testing of the program in a Linux environment, ensuring compatibility across different operating systems. Additionally, the VM setup eliminates the need to install Java on the host machine, simplifying the process of playing the game without any additional dependencies. Furthermore, Vagrant enables testing the program with a specific JDK version (openjdk 11, with the current setup) required to play the game, even if the host machine doesn't have the correct version installed. With Vagrant, the setup process only takes a few minutes and the VM setup can be done with a few simple commands.
