The project was primarily created for the programmers' contest, setted up by Small Science Academy of Ukraine. It's aim is creating a small library and some example programs for the lessons of informatics. There is a sort of lessons (I could not find their english name in the dictionary), where the pupils can be if they wish, and where they study something unusual - as example, solve problems from the mathematics contests or study programming by writing small games. The "gamELibrary" was written like a library for such a lessons, and the game and editor were written to let the pupils look at the implementation of some parts of the game or write own games based on this one.
