This contribution is part of a bigger project focused on teaching easy Hi-level programming languages for highschool teens (or even kids).
It is a ruby language game project using GoSu-library (GEMS) embedded to be used as a sample tutorial for beginners who wants to learn coding.
There are some implementations of players, a basic scenario, and some movements using the keyboards inputs. Although, it is a template for any other game.
Feel free to join and make contributions as much as you want, and please let me know! I will be happy to hear from you!
