Most of this was forked from an older engine I created when developping my other chess game: Aurora Chess
Yesterday I fixed mostly bugs that were already fixed on Aurora Chess, and bugs that appeared when tweaking with settings such as adding Fog of War mechanic as well as creating a Distinct Flag piece that is not in Aurora
The rules were pretty vague about using old code and engine, I intent to make this game visually more distintct from Aurora during this jam and perhaps develop the gameplay further as well.
