This is a shool project I did in 10th grade. The project is build upon gloop which allows to create visual 3d shapes in Java.
I've created this project for a few computer sience lessons to introduce my classmates into how to develop games etc. Docs and some Tasks are included in the project if you want to give it a try. The tasks are only in German so maybe try Google translate if you dont know german. Docs | Tasks
Have fun messing arround with this project.
