Because traditional chess is not epic enough.
This is a sandbox designed to play variant chess, particularly my variant Heaven and Hell (Rules). No rules are enforced, however. For maximum flexibility you can move pieces around as you like and play with the sandbox's two additional boards, status effects, new pieces, and various items/obstacles that can be placed on tiles.
The sandbox is implemented in Go using Raylib and Raygui.
Must be compiled with CGO_ENABLED=1.
