Great game! How did you do the cross platform? Xamarin, native or something else??
The web version was originally a straight recompile with emscripten but it was way too slow so it's a hybrid approach where the board engine is emscripten and the UI is rewritten with HTML/canvas.
I am just curious. What engine and development tools did you use? If I like a game, I want to know the backend tools that was used for developing.
