just search google for DoL or full name. I joined their discord you can find them in their blogs, the game is free, and everyone can mod the original the game(i did asked the owner and yes its free game and they shared their github). You cn share the modded game or just keep it for yourself. Its a game and its great starter for programmers to learn too. They have a separate website with modded of its original game.
