+
+The assignment to validate this course is to write a mini-game in Java. The game
+may use a graphical user interface with one of the frameworks seen in class but
+it doesn't have to. A pure text-mode game won't necessarily receive a
+lower-grade than a GUI one or be graded more severely. It should consists of a
+repository of Java code (some light scripting in other languages to package and
+build it is ok) and must be sent to me before the 30th of october (strictly
+before, that is, you have until 2023-10-29 23:59 UTC+1) under the form of a link
+to a `git` repository or an archive (`.zip`, `.tar.gz`, `.tar.bz2` or `.7z`)
+containing the sources and the sources only (**no compiled binary**).
+
+The project is meant for you to demonstrate your command of the concepts studied
+in class such as inheritance, typing or packages. The source code of your game
+_must_ include interfaces and abstract classes, so I suggest to you some sort of
+farming game where they occur naturally (because, usually, in those games the
+objects found or used form a tree of families sharing common properties —
+classes — or fulfilling some common purpose — interfaces) but there is no
+obligation. If you choose a different kind of game, please let me know in
+advance and explain how you plan to use interfaces and abstract classes in your
+implementation.
+
+There is no firm notation grid but the following criteria will be taken into
+account to give you a grade between 0 and 20:
+
+- Reuse of the object-oriented programming concepts seen in class:
+  + are those concepts used correctly ?
+  + are they used in a relevant way ?
+- Technical quality of the project
+  + have you documented properly the way to compile and use your program, for
+    instance with a README file ? (you shouldn't assume I use the same
+    development environment as you, i.e. "I just click the 'Run' button" is not
+    a proper compilation instruction so in the end everything should be
+    compilable fairly easily from the command line with `javac`)
+  + is it compiling when following these instructions ?
+  + does it run without flaws ? are there unhandled errors at run-time ? bugs ?
+- Quality of the code
+  + how easy to understand is your code ?
+  + how well are your variables, functions and classes named ?
+  + is your code clean from a typographic perspective ? (no extra spaces
+    trailing on lines, consistent indentation — tabs or spaces, pick your side —
+    and naming conventions — case, abbreviations or not). The code should be
+    homogenous enough that one can't know who has written what parts just by
+    looking at them
+  + are the comments appropriate ? (have you used them to document how your code
+    is used and works or abused them to caption the obvious ?)
+
+You will need an overall grade of at least 10 and a strictly positive grade in
+each of the first-level criteria above (concepts, technical quality, code
+quality) to pass.
+
+You may work on your project in groups of up to 3 students but I want all of you
+to work on all the aspects of your program: it is not ok for one student to only
+think about the gameplay while the other does the implementation. A global grade
+will be given for the group. Once your group is formed or you have decided to
+work alone please send me an e-mail to register your project.
