This is the final result of the project given as homework at my university. It is a simple game of Arkanoid with 3 levels and (epic) animations (that were definitely required to submit and not just something I wasted my time on)
The project comes with an ant config file (build.xml).
Install ant here: https://ant.apache.org/manual/install.html
Run ant compile in order to compile the project
Run ant run in order to run the project with all the levels.
Run ant run -Dargs="x y z w ..." in order to run the chosen levels in succession, where x, y, ... represent the indexes of the levels (starts with 1 and supports multiple of the same level). The normal ant run is equivalent to ant run -Dargs="1 2 3".
