+- GameWindow:
+  - displays all visual components used in the game
+  - stores the Snake object
+- FoodFactory:

+## JAR of the final version
+If you follow <a href="https://github.com/delvh/Snake/releases">**this link**</a> and click on release "Snake - almost beta", you can download the runnable JAR of how the completed project should look like. Unfortunately due to poor Version-Control-skills, the original code got lost and had to be rewritten, however it should resemble the executed code closely
